Hi,
I just noticed: Doing a simple "cat /proc/$$/map" panics the system:
kernel trap 12 with interrupts disabled
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc01f9ec3
stack pointer = 0x10:0xc6eefccc
frame pointer = 0x10:0xc6eefcd8
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 35 (cat)
kernel: type 12 trap, code=0
Stopped at _mtx_unlock_sleep+0xa3: cmpl $0,0(%ebx)

Is it just my setup or a general problem? If it happens only on my
system I can give further details.
