SG-4860 23.01 upgrade: degraded network + ichsmb0: interrupt loop + unable to reinstall?

McDing

Hi
I launched the 23.01 upgrade on my SG-4860 and that in itself seemed to be going ok. After rebooting however, I started noticing a very degraded network performance (some wired clients work, others don't, all devices on my wireless network dropped below 60% when they were at 98% before. Now wifi almost never works. I initially spend my whole day trying to troubleshoot wifi network, thinking something went wrong there, but after restoring everything to a known working state, the issue seems definitily to be on the SG-4860 side of things.

I finally decided that even though the update "seemed to have gone OK", I wanted to factory reset the device (and upgrade to ZFS) in case any system file or so got corrupted, which might resulting in bringing my network to a crawl.

I started the flashdrive & console process but after going through most of the booting, I never manage to get to a menu on the console. After about 300 lines I only get a never-ending loop of:
"ichsmb0: interrupt loop, status=0x60". Every 10-20 lines they get interrupted by some commands, but the loop never stops.

I am kind of at loss here what to do, as I cannot work with my degraded network and the restoring/reseting does not seems accessible either?

I saw the one line errata on the SG-4860, but is there anything I can do here at all?

Any help greatly appreciated

@mcding This was asked/pointed out in another thread recently:

@stephenw10 said in System General Logs flooded:

You can interrupt the boot process at the loader menu to reach the loader prompt. Then enter there:

set hint.ichsmb.0.disabled=1
boot

Then you can boot into the installer as normal

Hi @steveits
I saw the post but am not sure how to interrupt the boot process.
I tried 'esc', 'ctrl+d', 'ctrl+x' I believe but non worked...
Would you happen to know which one to use?
Thanks again!

@mcding Try this:

...before the timer expires.

@steveits perfect thanks!
Will give that a go.

I also just managed to further narrow down my degraded network issue: pfBlockerNG.
Deactivating it allowed all my network devices to be back online... it seems.
Had it uninstalled (keeping the settings) before the upgrade and reinstalled it after (also moved from DEV to stable). I didn't see any issues in my settings at first glance, but at least my network is now back.

@McDing Ran into this myself just now, on a 4860. Per the referenced thread it will be fixed in 23.09.

For posterity the loader.conf.local can be created at the end of the install. Go to a shell prompt instead of rebooting, and create file /mnt/boot/loader.conf.local containing:

hint.ichsmb.0.disabled=1
