Daily Kernel page faults

(1/2) > >>

inittab:
Hello, I'm running opnsense 22.7.11 within proxmox 7.3-4 on a protectli VP2420 - 4x 2.5G Port Intel ® Celeron J6412

I've been getting daily page faults where the opnsense vm will reboot, neither my pihole lxc on proxmox, or proxmox will crash or see any issues, just the opnsense vm.

I've attached the output from the latest crash. any idea's what might be going on here? I'm not doing anything out of the ordinary during crashes, it doesn't happen during high load or anything else, this latest crash I just had a youtube video going. Any help is appreciated, Thanks!

Maybe you want to disable IBRS. Set "hw.ibrs_disable" to "1".

You could also have a word with the hardware manufacturer. This looks fishy.


Cheers,

Thanks, I've set disable_ibrs in the tuneables and will see how this goes. if not I'll reach out to protectli

inittab:
Looks like same issue, set tunable for disable_ibrs, rebooted, and looks like it's still page faulting on the ibrs entrypoint. new log was too big to attach so is at https://pastebin.com/hTTEJjUm


I'll get in touch with protectli, any other ideas?

bob9744:
I have a vp2420 as well, which had been running well on 22, but a day or two after upgrading to 23 also had a kernel panic and rebooted (didn't notice til later). I've attached a log file as well, though the panic itself looks different.

I submitted it through the reporter as well if that helps - thanks in advance for any ideas!
