This is a reproducible OOPS for me. I mount the drive, cd into the
directory which it is mounted in, attempt to 'ls' the dir. On the first
attempt to 'ls' I get:
paranoia kernel: scsi1: ERROR on channel 0, id 0, lun 0, CDB: Request Sense 00 00 00 40 00
paranoia kernel: Info fld=0x0, Current sd0b:00: sense key Medium Error
paranoia kernel: I/O error: dev 0b:00, sector 96
paranoia kernel: scsi : aborting command due to timeout : pid 0, scsi1, channel 0, id 0, lun 0 Read (10) 00 00 00 00 18 00 00 01 00
paranoia kernel: hdd: timeout waiting for DMA
paranoia kernel: ide_dmaproc: chipset supported ide_dma_timeout func only: 14
After waiting a second or so for the bus to reset, another 'ls' OOPSes the
kernel. I've inline attached the output of the oops I've run thru our
friend ksymoops below.
The cd-r is an HP CD-Writer Plus (atapi with ide-scsi module). I can burn
CDs no problem, listen to music thru it no problem. This OOPS only occurs
when I try to use the drive to mount an iso9660 filesystem (ie. a data cd)
Thanks in advance for any help.

ksymoops 2.4.3 on i586 2.4.10-ac3. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.10-ac3/ (default) -m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
