Hello all,
My freebsd3.3-stable as of today panics with a page fault in kernel mode
when I try to mount a CD-ROM. I haven't used the CD-ROM player in a while
on this system, so I don't know exactly since when this is happening.
The output of gdb -k and dmesg follow. I've kept the dump so if more info
is needed, let me
know.
Gert-Jan
