I have a Supermicro SuperServer 6013P-8, with:

ahd0: <Adaptec AIC7902 Ultra320 SCSI adapter> port
0x4000-0x40ff,0x4400-0x44ff mem 0xfc300000-0xfc301fff irq 5 at device =
2.0 on
pci3
aic7902: Ultra320 Wide Channel A, SCSI Id=3D7, PCI-X 101-133Mhz, 512 =
SCBs
ahd1: <Adaptec AIC7902 Ultra320 SCSI adapter> port
0x4800-0x48ff,0x4c00-0x4cff mem 0xfc302000-0xfc303fff irq 5 at device =
2.1 on
pci3
aic7902: Ultra320 Wide Channel B, SCSI Id=3D7, PCI-X 101-133Mhz, 512 =
SCBs

Trying to install 5.1-CURRENT-20030709-JPSNAP or 4.8-STABLE on the
box gives a timeout error that will hang the disk in a state that
resetting the machine does not clear, and only power cycling will
clear. Ive replaced the disks with no change, but installed and
ran Redhat 7.3 on the box with no timeouts or errors.

The full dmesg is here:

And timeout is here:
