Ryzen 3 2200G randomly crashing



  • pfSense 2.4.4-p3 on B450 chipset on latest BIOS. Anyone had a similar issue? Just randomly crashes and reboots. It's not under a terrible amount of load or anything, but I'm lucky to have a 3+ day uptime...

    I've got a pfSense crash report if necessary that I can provide.


  • Rebel Alliance Developer Netgate

    Post the crash report.



  • Here you go.

  • do you have snort + barnyar2 as inline mode ? it seems to me a network card issue, Realtek RTL8111H could be the culprit

  • My bad Derelict, I meant to delete that other one in General but got distracted.

    I used to have barnyard configured on old hardware but I have it disabled now. I transferred the config over.

    The Realtek card is not in use for network traffic. I could try to disable that in the bios. I've had issues with Realtek cards in pfsense before and that usually just crashes the NIC driver, not the whole server. I think this is more of a FreeBSD kernel/cpu/chipset thing based on the crash report. Just my 2 cents though.

    There is this bug, but it was supposed to be fixed in FreeBSD 10.1 - https://forums.freebsd.org/threads/fatal-trap-12-page-fault-while-in-kernel-mode-on-new-server-running-freebsd-10-1-release-p10.51737/

    Nope that bug is completely different. The key part is the backtrace here:

    But this is not good:
    [zone: pf frag entries] PF frag entries limit reached
    You could increase the frags limit in System > Advanced > Firewall & NAT
    But really you are hitting that because of an unusually high number of fragmented packets you should try to find why that's happening and fix it.

    Steve



  • Ahh ok, I remember jacking up the fragments on my old hardware and that solved it then. I bet that's what it is. I guess the advanced stuff like that doesn't get transferred over in the config dumps when you move it to new hardware.

    I know what the fragments are. There is an NTP pool node behind this pfSense and it sees some heavy UDP connections, among other things...

    Thanks for tracking that down!



  • Ok I got another crash today, and today it's not showing the pf frag entries limit reached, but same kernel crash message.

    MBUs set to a million
    Frag packets set to 25,000.

    pfsense-crash.txt

    Any other ideas?



  • For kicks I've disabled MSI-X and went to MSI interrupts. We'll see if that has any effect.

    /boot/loader.conf.local

    hw.pci.enable_msix=0

    Hmm, that's different crash. Still in the network stack though:

    Nothing in the message buffer to help.....



  • Yeah, I've been reading about how Intel cards suck with MSI-X, so hopefully that's what it is. I guess time will tell.


  • Netgate Administrator

    That has not been my experience. Especially with em(4) which is very mature at this point.

  • @stephenw10

    https://www.intel.com/content/www/us/en/support/articles/000017506/network-and-i-o.html

    Maybe it's the amount of packets I'm pushing through my Gigabit Intel WAN? I'm pushing it pretty hard. 12 hours on MSI so far and no crashes and no degraded throughput or anything. Probably a slight increase on CPU, barely 3% if that.



  • Well, 1 Day 11 Hours 08 Minutes 36 Seconds uptime since going to MSI. Knocks on wood



  • @Zermus

    This surprises me as well after reading through this thread - Intel cards are generally top tier and perform very well with pfSense. What specific Intel card / chipset are you using?



  • @tman222

    WAN - Intel Gigabit CT PCI-E Network Adapter EXPI9301CTBLK
    LAN - Intel X520-DA2 (The real Intel, not the 10GTek knock off, Multiple VLANs using only one port)

    LAN - Intel X520-DA2 (The real Intel, not the 10GTek knock off, Multiple VLANs using only one port)

    Which one of those two was / is giving you trouble? Looking at data sheets and product briefs, both of those cards support MSI-X. Also, just to doublecheck, are you running pfSense on bare metal or inside a VM? Have you tried adjusting any of other tunables on the cards or is everything basically running with stock settings?

    Come to think of it now, I did have one EXPI9301CTBLK adapter seemingly go bad on me a couple years back. Was running in a Windows desktop machine though. For some reason one day it stopped passing gigabit speeds and nothing I did would fix it (reinstall, change cables, etc.). Replaced with another card and all was well.

    I think the chipset in the Intel CT adapter is targeted more towards desktop/laptop applications. If you're interested in replacing it with something a bit higher end, these HP Intel i210 based cards should work well, are fairly inexpensive, and use the igb driver in FreeBSD:

    https://www.amazon.com/Intel-I210-T1-Network-Adapter-E0X95AA/dp/B00ESFF2JC/
    https://www8.hp.com/us/en/products/oas/product-detail.html?oid=5383389

    Hope this helps.



  • Hmm, I'll try to swap out the Intel CT with the I210. The weird part is that the system was stable on older hardware with the same NICs, the system was based on an AMD A8-7600 Kavari (Steamroller). Unfortunately the motherboard started flaking out on that system though, which lead to the Ryzen rebuild. Right now with MSI interrupts the system seems stable for about 2 to 3 days but now experiences hard crashes where I get no crash reports.

    Extended 12 hour memtest run came up with no errors, so I'm fairly certain hardware is good in this case. I'm starting to wonder if it's just Ryzen and FreeBSD bugs creeping up that I'm hitting.

    That's a good point - I wonder if support / stability will improve with FreeBSD 12.0 (which pfSense 2.5 will use).
