What's the recommendation for avoiding system lockups when using
the SVGA server with a SCSI kernel loaded?

If I boot an IDE kernel, all is well.  If I recompile the same kernel
with SCSI (aha7xxx) enabled, the system freezes when I start X.

I don't see any IRQ conflicts in cat /proc/pci...

PCI devices found:
  Bus  0, device  11, function  0:
    SCSI storage controller: Adaptec AIC-7881U (rev 0).
      Medium devsel.  Fast back-to-back capable.  IRQ 4.  Master Capable.  Latency=32.  Min Gnt=8.Max Lat=8.
      I/O at 0x9200.
      Non-prefetchable 32 bit memory at 0xe0804000.
  Bus  0, device  10, function  0:
    VGA compatible controller: Matrox Millennium (rev 1).
      Medium devsel.  Fast back-to-back capable.  IRQ 10.

  Bus  0, device   7, function  1:
    IDE interface: Intel 82371SB Natoma/Triton II PIIX3 (rev 0).
      Medium devsel.  Fast back-to-back capable.  Master Capable.  Latency=32.
      I/O at 0xf000.
  Bus  0, device   7, function  0:
    ISA bridge: Intel 82371SB Natoma/Triton II PIIX3 (rev 1).
      Medium devsel.  Fast back-to-back capable.  Master Capable.  No bursts.
  Bus  0, device   0, function  0:
    Host bridge: Intel 82441FX Natoma (rev 2).
      Medium devsel.  Fast back-to-back capable.  Master Capable.  Latency=32.

Any suggestions?  

Regards,
Jason.
