#4 Centris 650 unstable with external SCSI

I cannot get my Centris 650/40MB RAM with an external 4 GB SCSI drive (fireball mechanism) to work reliably. It won't make it through the install process without crashing. I have installed in the past without incident when I wasn't trying to use the external drive, but now it will crash repeatedly during install, usually when extracting from the base_2_2 file. I'm trying to install potato, and I've tested both drives (internal and external) with both the Apple utility and Debian's own check during install. After one of the crashes, I can usually recover by rebooting, letting fsck try to repair the disks, and then usually having to run it again myself. Then, I make it back to the point I was at, try to install some software, and usually during unpacking it will crash again.

I've tried 3 different partitioning schemes (been at this 4 days)

Scheme 1:
sda6: Root
sda7: Swap
sda8: /tmp
sdb3: /usr
sdb4: /home
sdb5: /var

Scheme 2:
sda6: Swap
sda7: Root
sda8: /tmp
sdb3: /usr
sdb4: /home
sdb5: /var

Scheme 3:
sda6: Swap
sda7: Root
sdb3: /usr
sdb4: /var
sdb5: /home

Again, I'm able to eventually get the system installed, but it's unusable due to it's instability. I don't think the NCR5380 SCSI problem applies to this machine, so I didn't follow those install instructions. I haven't tried just letting the machine sit without doing anything to see if it crashes. I can't make it through the install procedure without a crash, and if I can recover from it, it will crash again during a software install.

I'm willing to perform additional tests if you need me to.

    Try adding mac53c9x=1,0 to the kernel options (same problem
    as the 5380 reselection race)

    Could this be a 10 Mbs instead of 5 Mbs problem?
    The 25 pin external connector (db25) has a 5 Meg speed limit

    Should be fixed in the current 2.6 kernel.
