[1.] One line summary of the problem:
cp -a from cdrom to hard drive produces lost interrupt message
[2.] Full description of the problem/report:
I put a cd into cdrom drive and mount it. I then issue the command:
cp -a /mnt/cdrom/* /mnt/rw1
The copy proceeds normally for some variable amount of bytes before
producing the following output in /var/log/messages:
Apr 2 12:49:11 localhost kernel: hdb: DSC timeout
Apr 2 12:49:21 localhost kernel: hdb: lost interrupt
Apr 2 12:49:21 localhost kernel: hdb: cdrom_read_intr: data underrun (4
blocks)
Apr 2 12:49:21 localhost kernel: end_request: I/O error, dev 03:40
(hdb), sector 102860
Apr 2 12:49:32 localhost kernel: hdb: lost interrupt
Apr 2 12:49:32 localhost kernel: hdb: cdrom_read_intr: data underrun (4
blocks)
Apr 2 12:49:32 localhost kernel: end_request: I/O error, dev 03:40
(hdb), sector 102864
At this point no more bytes are copied and I get a continuing series of
the above messages. After some time I'm able to kill the cp command and
unmount the cdrom, but I'm unable to eject the cd. The drive light
continues blinking and I'm forced to reboot to stop it.
