I am debugging a KLD and I have got the following panic inside an
interrupt context:

fault virutal address = 0x1080050
...
interrupt mask = bio
kernel trap: type 12, code = 0
Stopped at vwakeup+0x14: decl 0x44(%eax)

Where eax is 0x108000c and vwakeup() is called from biodone().

Since this panic occurs in an interrupt environment, I have no idea how to
trace it. Is there a way to find the bug by tracing or what is the prime
suspect in this case.  Thanks!
