Screendump showing the kernel panic.
Dear esteemed FreeBSD developers,
I am in a little desperate situation... :)
The developers of iXsystems behind FreeNAS are running the latest FreeBSD. They
told me to post here as this is 100% FreeBSD related.
When I'm booting up the system, I get a kernel panic around 50% of the time.
I'm running the latest firmware and bios on the IPMI BMC, Supermicro
motherboard, Avago/LSI SAS3 HBA and the Chelsio NIC.
>From the log-files it seems the CPU and the FreeBSD kernel don't like each
other.
I have tried to enable debug mode in the OS, but the panic happens before
anything useful is logged. I submitted the log to the FreeNAS developers and
they said they couldn't find anything useful in that log as the panic happened
too early.
If you take a look at the attached JPEG, perhaps you can spot something? Their
recommendation was to disable the Machine Check Architecture support by
setting loader tunable hw.mca.enabled=0.
I haven't done this yet. Shall I do it?
The CPU is 8 cores with 16 threads each.
Is there anything that I can do to assist you to remedy the issue?
Kind Regards,
Rikard
P.S.
I could of course install the latest stable FreeBSD version on a disk but i
find it meaningless as the FreeNAS kernel is the same as the FreeBSD. The
panics all appear on FreeNAS 11.1-U4, 11.1-U5, 11.2-latest beta
