Hi,

Hmmm.
Fresh -current, fresh patch.
 (Hunk 2 still doesnt apply cleanly, but this seems to be irrelevant
 for the problem)
Old symptom:
...
mounting root from ufs:/dev/ad0s3a

Fatal Trap 12: page fault while in kernel mode
fault virt. addr. = 0x20
fault code = superv. read, page not present
IP = 0x8:0xc0176b61
SP = 0x10:0xc03d6b7c
FP = 0x10:0xc03d6b8c
CS = base 0x0, limit 0xffff, type 0x1b
     DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
curproc = 0 (swapper)
....

Can I get from kernel.debug and the IP-address the faulting code
postmortem for shure?
`nm /boot/kernel~/kernel | grep c0176b` gives:
c0176b4c T dsname
c0176bf8 T dsopen


Bye!
