Lets see if I can get some more info that might help.
1. EVMS 1.2.0 is running on 2.4.18 w/initrd and tons of extra stuff
compiled that I don't use. On 2.4.20 + evms 2.0, I tried using a
limited kernel without initrd.
3. Partitions...
sda is just strait ext3 linux partitions (no evms)
sd[b-e] is a raid 5 volume (evms)
4. Libraries
libc6 deb package 2.3.1-14
5. Kernel...
Only the DM+evms patches were applied to the kernel. No special drivers
are used.
6. Some scsi info...
I compared scsi and pci info from /proc with 2.4.18 and 2.4.20. They
look the same, except 2.4.20 has some extra eeprom output. I listed the
2.4.20 kernel output below.
Dual channel (built onto the motherboard).
You can see the system boots off channel B, (sda)
Channel A has four disks (sd[b-e])

I'm starting to think someone broke aic7xxx in 2.4.20
