Hi :
I just supped the new kernel source, and it panics while boot.
I think maybe it is b'cos of some changes in these days,
b'cos my Jan-7 kernel runs fine. (before the Jan-8 subr_diskslice.c
change)
It panics at subr_diskslice.c, while mount_msdos. I have 3
dos partitions mounted.
1. /dev/sd0s1 : 0 - 500MB Primary
2. /dev/sd1s1 : 0 - 400MB Primary
3. /dev/sd2s5 : 0 - 1G Logical
