bG3+damaged CD=crash

[Giuliano Pochini]

My blue-G3 hangs completely when I try to read a CDROM with some
errors. The whole system freezes and the only cure is reboot (no
logs, no errors, no panics, no oops). My older 7300 simply told
it couldn't read the disk. Is it a known bug ?

My config: G3 blue 350, IDE CDROM, kernel 2.2.16p (the one with
usb patches).

Perhaps I'll buy a SCSI CD, I hate IDE junk.

USB related panics

[Giuliano Pochini]

Sometimes my G3 crashes with the error: "had to kill usb urb",
then the kernel panics with -I don't remember well- "reschedule
in interrupt handler" or something similar. /:-6
Yes, I know the usb support is still beta, but this one should
be fixed ASAP.

Which kernel are you using ? The old backport or the new one in my -ben1
kernel ?

Ben.

I don't remember what patchset I'm using, but I believe it's not
your one. At boot it tells 2.2.16p. I can't be more precise now because
I'm at work and my G3 is at home... without serialport==nomodem GRRR!!!

Maybe it's a bad CD?  Chances are if it crashes one machine and another
won't read it, that the CD-ROM itself is bad, not the reader....  If you
purchased the CD (as opposed to burning it yourself), get in contact with
the LinuxPPC people and ask for an exchange...

Your 7300 (I think, and AppleSpec backs me up) has a SCSI CD-ROM, so it's
probably not the drives.

Yes, it IS bad.

Ehmm, no.  This CDROM is a backup copy of all junk I d/l from the net. It's
content is not important. What I mean is thet if I try to read a file Linux
creashes.

cp /mnt/cdrom/foobar.tgz /home/pochini/    ---> Linux hangs completely

Doing the same on the old 7300 w/ SCSI CD reader if tells me it can't read the
disk and continues working happily.

The problem is the pmac IDE software driver. Trying to read the same CDROM om
my PC gives an error and does not crash.
