Major Failure 2.4.0-test12 Alpha

Major Failure 2.4.0-test12 Alpha

[Leslie Donaldson]

Hello,
  Just writing in to report a bug in 2.4.0-test12.
Hardware:
  PCI-Matrox_Mill
  PCI-Adaptec 39160 / 160M scsi card
  PCI-Generic TNT-2 card
  PCI-Sound blaster -128 (es1370)

CPU 21164a - Alpha

Problem:
  There is a race condition in the aic7xxxx driver that causes the 
kernel to lock up.
I don't have a kernel dump yet as the machine reported by it'self..
This problem has been easy to reproduce. ergo about 3 crashes a day.

Solution:
  Sync often and pray.

Misc:
  As soon as I get a real dump I will post a followup to this message.

Just to add my 2 bits, I have an AlphaServer 1000A that has a pci-pci
bridge.  I put an adaptec 2940UW on the primary pci bus.  After attempts to
mke2fs on a raid0 set (using 2.2.17 /w and w/o raid patches), it would just
lock and I'd have to reboot the machine.  I was able (IIRC) to remount r/o
the other disk that I had.

I'm also seeing this on 2.4.0 proper with almost the same hardware:
 SCSI storage controller: Adaptec AIC-7881U (rev 01) (aic71xxxx driver)
VGA compatible controller: Matrox Graphics, Inc. MGA 1064SG [Mystique]
(rev 03)
SB Vibra16X sound card.

I swap to scsi as the ide performance on this board just blows, I get into
a heavy swap situation and *boom* deadlocked.
