Description D C 2009-04-13 12:10:03 UTC

Recompiling the kernel on 7.1-RELEASE (amd64 platform) with k8temp and smbios in the kernel configuration somehow breaks geom_mirror autodetection and is therefore unable to boot from the /dev/gm0 mirrors.

The previous root device /dev/gm0s1a is now detected as both /dev/gm0cs1a and /dev/gm0ccs1a upon booting the new kernel.

Fix: 

Remove "device k8temp" and "device smbios" from the kernel configuration file.
How-To-Repeat: cp /usr/src/sys/amd64/conf/GENERIC /usr/src/sys/amd64/conf/VOODOO
echo "device          k8temp" >> /usr/src/sys/amd64/conf/VOODOO
echo "device          smbios" >> /usr/src/sys/amd64/conf/VOODOO
cd /usr/src
make buildkernel KERNCONF=VOODOO
make installkernel KERNCONF=VOODOO
reboot

Problem description sounds quite weird.
Will you be able to provide more details if you can still reproduce the problem?
