I have both a dvd RW drive & a cd rom drive connected the second ide
interface on my motherboard with a via chipset, using pata_via I see
timeout messages in the log & after some time both drives lockup and are
unable to mount any disks.
This problem is present in at least 2.6.22 & 2.6.23-rc5.
This is a AMD Athlon X2 smp machine running fedora -- untainted.
sorry I didn't spot this sooner but I don't use these drives all that
often.
Any suggestions for what is going wrong or how to get any more debug
info?

By this point neither drive will mount a disk.
