2.4.18: many IDE errors

[Eyal Lebedinsky]

I have six disks in the machine, each a master on the cable. Two are
on the on-board controller and Four are on two PCI ATA-100 cards.

I am getting disk error (BadCRC) on all disks, intermittently.

I upgraded from RH 2.4.9 (with SGI xfs) to 2.4.18+xfs. Same problem.
I then applied the 2.4.18-rc1 IDE patches with no improvement (well,
the four 160GB disks are now fully visible and not clipped to 28bits
which is a nice surprise).

I checked the memory, replaced the power supply with a hefty 400W,
I even used a recent mobo (Gigabyte GA-6VTXE). No beef, practically
the same rate of errors.

I do not believe all six cables are bad (80w all). This is a UP, and
I did not enalbe local APIC. Should I?

Any ideas where to go from here? On request I have boot messages
(with errors) and lspci output - I prefer not to overload the list.

The setup is two WD 60GB disks (hda/hdc) which host the root fs (ext2)
a working area (md2=RAID0, most of the space) and an xfs log
(md1=RAID1).

hde/g/i/k are Maxtor 160GB, RAID5, xfs (with external log on md0).

I get errors intermittently on all, here is an example after a boot
following the creation of the raid5 (so a sync was running for about
two hours).
