SG-5100 takes over 20 minutes to boot after eMMC failure
-
@gabacho4 the forum indentation is a bit confusing indeed. I replied to the post from @stephenw10 with the 'hack' and it then shows that post as a reply to Stephens post, but also as a new post at the bottom of the whole topic, with just a small reference to the fact that it is a reply to an earlier message. Anyway, the life saving configuration change is this:
Create the file /boot/loader.conf.local and add to it:
hint.mmcsd.0.disabled="1"It is as simple as that :-)
The only thing I am not sure about is what happens to this setting when you do a regular upgrade to a new version of pfsense. @stephenw10 does it get preserved?

I'll have to try that later when I'm able to reboot my 5100. Sounds promising.
-
Just to make sure I understand the hack right - it’s merely telling pfSense to ignore the first of the storage options being provided by the BIOS therefore causing pfSense to turn to the M.2 right away rather than trying the eMMC. Correct? If so, this seems like something Netgate could code in as part of the pfSense config and make a toggle for in the GUI (“ignore eMMC at boot”) and we’d all happily be on our way. If coded, it would be persistent across any installation/upgrade or config restoration. Could it be that simple?
-
@gabacho4 That's how I understand what this setting does indeed. And I guess this setting could be done in pfsense, however, I feel that it is a design flaw of these Lanner boxes and should be fixed in BIOS. But I would be happy with either ;-)
-
@haraldinho fair enough point. I wonder if ALL of their devices with eMMC suffer from this. If so, the coding with GUI would make sense unless they can get BIOS updates for all the devices. If the 5100 is alone in suffering from this, the you’re right; a final fix from Lanner should be secured. Ultimately I just need a device that I can rely on 100%. I’m pretty spooked right now considering my very remote router could become (if not already) very dangerous to reboot or update. Yikes!

The boot loader hint didn't work for me but I didn't think it would. My 5100 still appears to hang after I issue a reboot from the webConfigurator. The power light stays lit (good) but so do the lights on the igb0 and igb1 ports. They do this on a cold boot too but after a few seconds, they clear and then the boot process resumes. Still seems to be a BIOS issue.
FWIW, even after adding the boot loader hint that @stephenw10 suggested, pfSense/FreeBSD still sees the eMMC (via dmesg):
sdhci_pci0: <Intel Denverton eMMC 5.0 Controller> mem 0xdff9a000-0xdff9afff,0xdff99000-0xdff99fff irq 16 at device 28.0 on pci0 mmc0: <MMC/SD bus> on sdhci_pci0Ideally there'd be a way to disable that completely in the BIOS.
-
@hayescompatible Hmm, that's a bummer. I must say I also have that same line still in my logs after the hack. So there is no difference there between our setups.
NOTE
after you made the modification, you need to power cycle your box once more to get the line loaded and effectuated. After that power cycle, warm reboots from the web configurator work again for me.Some things you can check:
- If you disable "Quiet mode" in BIOS and do a boot, do you see a difference in your logs with and without the hack?
For me all the references to timeouts like the one below went away in the logs (next to the fact I can now issue a Warm Reboot from the WebConfigurator.

Yes, loader.conf.local is preserved across a firmware upgrade.

mmc0: <MMC/SD bus> on sdhci_pci0That's the mmc bus. mmcsd0 is the first mmc device on that bus which is what has been disabled.
If there was an issue with the bus or the controller you could disable those instead. Disabling only the emmc storage device itself is the minimum you need to do to stop is trying to read it.

I just added a drive in a 5100 and it works fine. Actually, seems a bit snappier.

I do sysadmin mostly on Linux boxes so I know my way around
viand such. The file exists there, I checked the quoting method and from what I understand,dmesgconfirms the eMMC is no longer being recognized (if it was at all before).I wonder if the state of the eMMC is a thing? Mine seems completely dead: it used to give me timeout errors but the last time I tried specifically accessing it (during a clean install of pfSense and accidentally selecting the eMMC as the install root), the installer just froze. I gave up after several minutes of waiting. IIRC (possible I don't), I would get some timeout errors and the installer would eventually raise an error.
In any event, this trick isn't working for me. I'll try to schedule some downtime in the next week to try again.

@haraldinho You can disable it completely in pfSense and prevent those errors.
Create the file /boot/loader.conf.local and add to it:hint.mmcsd.0.disabled="1"But that doesn't help with the slow boot in the BIOS.

@haraldinho I think the part I've emphasized here is relevant. My 5100 hangs either before or during POST on a warm boot. The boot process hasn't even begun yet. So this makes me even more skeptical that the loader hint would be applicable in my situation since the OS isn't being loaded yet.
-
Yeah, if it's hanging at POST before it even tries to boot from SSD then adding a loader variable won't make any difference.

Thanks for confirming that. I also just confirmed that myself by rebooting the 5100 before I left the house this morning. Here are the last messages I see from pfSense as it is rebooting:
pflog0: promiscuous mode disabled Waiting (max 60 seconds) for system process `vnlru' to stop... done Waiting (max 60 seconds) for system process `syncer' to stop... Syncing disks, vnodes remaining... 0 0 0 0 0 0 done Waiting (max 60 seconds) for system thread `bufdaemon' to stop... done Waiting (max 60 seconds) for system thread `bufspacedaemon-0' to stop... done Waiting (max 60 seconds) for system thread `bufspacedaemon-2' to stop... done Waiting (max 60 seconds) for system thread `bufspacedaemon-6' to stop... done Waiting (max 60 seconds) for system thread `bufspacedaemon-1' to stop... done Waiting (max 60 seconds) for system thread `bufspacedaemon-5' to stop... done Waiting (max 60 seconds) for system thread `bufspacedaemon-3' to stop... done Waiting (max 60 seconds) for system thread `bufspacedaemon-4' to stop... done All buffers synced. Uptime: 7h50m45sAfter an hour and a half, it never came back up so it is definitely hanging on warm boot, it's not just a delayed startup.
The POST codes that come up in the console on a cold boot are A2 99 B2. On a warm boot, there are no POST codes. I'm hopeful a BIOS update can address this soon.
FYI @haraldinho just to follow up on my last message, I can confirm the loader.conf.local file is loaded:
FreeBSD/x86 bootstrap loader, Revision 1.1 Loading /boot/defaults/loader.conf Loading /boot/defaults/loader.conf Loading /boot/device.hints Loading /boot/loader.conf Loading /boot/loader.conf.local -
quick question for the group - when you installed the m.2 sata, did you have to do anything special in the BIOS to get it recognized as the primary boot device or is that automatic? I have someone who is going to help get an m.2 and pfsense reinstalled on my remote router and I just want to understand the process as best as I can in advance. Unfortunately, I won't get my m.2 here until later this month due to the time it takes to get USPS overseas. The Netgate documentation on this process suggests it should be basically automatic but I'd rather make sure rather than run around in circles. Thanks!
-
You do have to change the boot device order. Or at least I have had to when I have done it myself.

You will need to go into the BIOS to change the boot order but it's a pretty easy thing to do. What wasn't clear when I went through this is that the SSD has to be formatted UEFI or you won't be able to select it as a boot device.
-
@hayescompatible is that something you do when installing pfsense or when/how? There seem to be a lot of little details missing from the guide.

See https://docs.netgate.com/pfsense/en/latest/install/install-walkthrough.html - you would choose "Auto (ZFS)" then set the partition scheme to one of the UEFI options.
-
@hayescompatible ah ok. That part is easy. I was afraid you were going to tell me it was something more obscure. Phew!
-
You can boot from eMMC or SSD as a legacy boot device as long as CSM is enabled.
