2.4.20-pre5-ac1 still crashes with ide-scsi

[konsti@ludenkalle.de (Konstantin Kletschke)]

Hi there!

I wanted to switch from 2.4.19-preX-acX because this release has had
Problems with the sound latency on my Computer. I thought it is my fault
or my hardware broken, but the Problem was reproduceable by doing

tar xzf linux-2.4.16.tar.gz ; cd linux
bzip2 -dc ../patch-2.4.17.bz2 | patch -p1
...

and so on. all the time all soundplayers with kernel or alsa drivers
crackled or paused (0.25s) playing.

This Problem occured even on console with no X and NVdriver (never been
loaded in session).

With 2.4.20-pre5-ac1 the Problem seems to have gone, I was not able to
reproduce it until know (runs 4 hours now, with reboots).

Otherwise, like in all ac kernels between 2.4.19-acX and 2.4.20-pre5-ac1
ide-scsi does not work.

sorry, the output is not well formatted, because the last two lines are
repeated print to the console and are editing vith vim impossible ;-)
After 20s the Computer hangs completely...

I use an Soyo Dragon Ultra with KT333, the IDE disks attached 
two the highpoint 372 controller and the cdroms attached two the via controller.

  Bus  0, device  15, function  0:
      RAID bus controller: Triones Technologies, Inc.
      HPT366/368/370/370A/372 (rev 5).            IRQ 12.
      Master Capable.  Latency=120.  Min Gnt=8.Max Lat=8.
		  
This is the cause I have to use the ac patches because the hpt372 is not
working with vanilla kernels...

The cpu is an XP1800+
