this is the results of when I am unzipping a file from my cd-rom onto my
dos machine under os/2... the cdrom is mounted via nfs...
this message is repeated 6 times before the panic:
nca0/4/0 (cd0) timed out
this is the panic message:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xefc45734
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf010bab2
code segment = base 0x0, limit 0xfffff, type 0x1b

processor eflags = interupt enable resume, IOPL=0
current process = 108 (nfsd)
interupt mask = net tty bio
here is the results that pertain to the problem from dmesg:

nca0/4/0 too many parity errors, not logging any more
if you guys need a copy of my kernel I can put it up for download...
also... is there any plans of implimenting SCSI 1 audio commands...
Thanks for all the help you guys have provided...
