Does hardly matter, since it patches the kernel at all. If there are
problems, re-test with baseline ftp.*.kernel.org kernels.

Use a reliable hardware RAID if you're for reliability. Note
RAID-mirroring does not help against any of the other problems that you
experienced.

You problem if you're buying an ATAPI CDROM drive. Get a good SCSI
adaptor and never think about DMA again. Consider getting a
multiple-IDE-disks-to-SCSI-adaptor.

It could be a RAID problem, it could be a hardware problem.

So you're in trouble. If you're willing to test, you might eventually
get fixes. If you're unable to test, you're not getting fixes at all.
