oops in 2.2.6 in sys_munmap()

last night an oops killed my 2.2.6 system (486) when trying to run `md5sum'
on all files on a ATAIP CDROM (/dev/hdd).
after reboot, the same operation did not crash the PC again, so I can't repeat:(

since the system was completely dead I only noted the EIP of the two oops:

1st:
invalid operation: 0000
EIP c011ac95 (sys_munmap + 5)
process running: md5sum

2nd:
kernel NULL pointer dereference at 0000002b
EIP c011ad7b (exit_mmap + 0x0b)

relevant part of Systemmap:

c011aa30 T do_munmap
==> c011ac90 T sys_munmap
c011acd0 T build_mmap_avl
==> c011ad70 T exit_mmap
c011ae80 T insert_vm_struct

sorry that I can't give more information,

Harald
