aic79xx+ASC39320A crash

[Bjarne Thomsen]

I have had this problem with an Adaptec ASC-39320A for more than 2 years
(using the x86_64 version of the aic79xx driver).
The 39320A board has been tried on the Tyan 2882 and 2885 MBs with
the same result: I can copy a few small files, byt when I try to
copy a directory tree with a few hundred MB the system freezes
without any traces in the syslog or on the screen.
Two older Ultra 160 Adaptec boards work fine with the 2 Tyan MBs.
The raid option has been disabled for the ASC-39320A.

Tho years ago I gave up, but I have now tested the board
with some newer linux distributions using the Tyan 2885 MB
with the latest available BIOS (for both 2885 and 39320A):
ubuntu 6.06 LTS x86_64 (2.6.15 kernel)
Mandriva 2007 x86_64 (2.6.17 and 2.6.19 kernels)
Fedora core 6 (2.6.18 kernel)

The symptom is the same: the system freezes during the copy
of files from an IDE harddisk to a SCSI disk on the 39320 controller.
I am about to give up, again.

Any advice is welcome.

Is there any crash dump or panic information on your screen?

Also, try resetting the board to defaults in it's BIOS and see if that
makes a difference.
