https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230511 Bug ID: 230511 Summary: Kernel panic on Xeon gold 6144 Product: Base System Version: 11.1-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: energyrikard@gmail.com Created attachment 196064 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D196064&action= =3Dedit Screendump showing the kernel panic. Dear esteemed FreeBSD developers,=20 I am in a little desperate situation... :)=20 The developers of iXsystems behind FreeNAS are running the latest FreeBSD. = They told me to post here as this is 100% FreeBSD related.=20 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.=20 >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 happe= ned too early.=20 If you take a look at the attached JPEG, perhaps you can spot something? Th= eir recommendation was to disable the Machine Check Architecture support by setting loader tunable hw.mca.enabled=3D0. I haven't done this yet. Shall I do it?=20 The CPU is 8 cores with 16 threads each. Is there anything that I can do to assist you to remedy the issue?=20 Kind Regards,=20 Rikard P.S.=20 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 --=20 You are receiving this mail because: You are the assignee for the bug.=
