:hey,
:
:I just got this double fault when I was doing some layered mounts:
:
:Fatal double fault
:eip=0xc034a27a
:esp=0ce2426ffc
:ebp=0xe2427000
:
:...
:trapwrite(0,c64e0760,0,0,0)
:
:I'll look the symbols up.  I guess that was a stack overflow, the second one.

    The symbols might give me a clue.  Considering the value of %esp it
    certainly does look like stack overflow.

    nm -N kernel.debug | less ... look for procedure containing %eip above.
