Driver bug ?

System: Linux 2.0.30 (also 1.2.13 and 2.0.28)
(Linux and BSD NCR810 driver)
adapter: NCR810 (active termination) (Symbios 53C810 chip)
Harddisk: HP C3325A Rev: 6066
Termination: OK
Cable: 50cm and OK
Other devices on SCSI bus: none
Problem: My harddisk crashes when running a (faulty) program.
When using a program of which I know has got a bug in it (it creates a
doubly linked list and uses the pointer of an object after calling free)
my harddisk crashes. (100% of the time) The first time it happened was
using kernel 1.2.13 (not using the program I currently use to crash my
system) but then I was not able to reproduce the problem. Currently I
am.
What happens ?
The driver tries to reset the drive. Sometimes this succeeds and the computer
continues. Most of the time the drive just locks up and I have to cut the
power supply to get started again (reset button will reset the computer but
it will hang when the NCR810 tries to detect the HD)
The things I've tried:
1. Changed the system memory
2. Tried another NCR810 controller, this one used passive termination.
(also a SYMBIOS 53C810)
3. Tried another video adapter (I just got a new one just before
the problem occured on a daily basis)
4. Putting the driver in FAST SCSI2, Sync mode etc.. and all combinations
5. Put the drive in SCSI (not SCSI2) mode (changed jumper on drive)
6. Used the BSD instead of the Linux driver.
7. Pulled the power plug out of the drive and reinserted it. (very
hard reset of the drive)
8. Tried to trace the bug by enabling the debug messages but when I do
this the system won't crash. (I could fix the problem by always
producing debug messages and sending them to /dev/null :-)
9. Changed the SCSI ID of the drive (and didn't expect it to work)
Any help would be ... helpfull :-)
-------------------------- /var/adm/syslog (logged on remote computer)
The return code varies, I've seen a0 and 93 (nothing else)
SCSI disk error : host 0 channel 0 id 0 lun 0 return code = a0
The sector at which the error occurs varies (any value)
The driver did not complain about the revision with the other NCR810
controller. (which also crashed)

It will keep doing this until the power is cut.
