Hi,
I have seen this panic a few times on a Gigabyte E350N-USB3 running 8-STABLE.
I have only seen it while in X, but then the machine is always in X. At first,
I just got these hangs, so bought a PCI-express RS232 card and could see these
at last. For some reason it does not go past this, so I have not been able to
get a dump yet.
Have anybody an idea of why this is or how to debug it further? I searched
the archives and found something similar about a year ago, but it looks
like it was solved with a fix that got committed.
http://www.freebsd.org/cgi/query-pr.cgi?pr=140338
I have now disabled mca in loader.conf with 'hw.mca.enabled="0"' and I have
not seen that panic again. I do occasionally see a panic in devfs_open(),
but I guess that should be handled in another thread.
The kernel is basically a GENERIC kernel with puc uncommented and the
following in loader.conf
vm.kmem_size="12G"
hw.mca.enabled="0"
zfs_load="YES"
ahci_load="YES"
xhci_load="YES"
amdtemp_load="YES"
ng_ubt_load="YES"
uplcom_load="YES"
Here is the panic message and after that dmesg.
John
