I believe the conclusion was made that this occurred with most WD drives (interesting about the WD == IBM part, I did notice he mentioned that in -current a few weeks ago as well). I had a WD20 gig that would just hang, and a number of other people had similar problems. (Theirs would log "Lost Disk Contact" in the dmesg as their root dev wasn't a UDMA66 drive) Unfortunately, the discussions occurred while the mailing list archive was kaput (WD Drive on UDMA66? =]) so it's not archived where I can find it. Seems to only happen with the ata driver, IIRC. -- Marius Strom Professional Geek/Unix System Administrator Alpha1 Internet http://www.marius.org/marius.pgp 0x42C74CBA *UPDATED PGP KEY 2/24/2000* In theory, there is no difference between theory and practice... ...In practice, there is a big difference.
