I just received the following upon mounting a CDRW disk in my
HP-7200i attached to /dev/hdc using scsi emulation (/dev/sr0)
under 2.0.36.

2 root@red:/burner# scsi : aborting command due to timeout : pid

I've been receiving many such errors as of late on this drive as
well as other cdrom drives in my system. The mobo has a VIA MVP3
chipset. NO DMA/UDMA is being used on this system at all.

The above cd was mounted, and then a "find . -name "ls-*"" was
done to locate all ls-lR files. at the same time, I used
midnight commander to completely copy the contents of the CD to
my hard drive for modification prior to reburning a new image.

Neither program completed. ls died giving the above error.
Shortly after, midnight commander gave a red error window
showing: cannot read source file, input/output error(5).

I just told midnight to "retry" here is my syslog entries for the
entire event:

Any thoughts as to what could cause this? Faulty driver? Faulty
motherboard? Chipset? Dirty drive? Any ideas or
fixes/suggestions are greatly appreciated.

Thankx
