with kernel 2.0.33 (both with and without SMP), I found the following strange
warning amoung the boot messages:
....

The same text also appeared with kernel 2.0.32 + aic7xxx-abort-Nov05-32.patch.
How do I "verify the driver settings" etc?
--------------------------------
My configuration:
Tyan Titan pro Dual Pentium Pro board with 2 x PPro/200MHz
128MB RAM (mem=127M in lilo.conf)
SMC Ultra ethernet card
The SCSI adapter identifies as
Adaptec AHA-2940 Ultra/Ultra W BIOS v 1.23
This is /proc/scsi/aic7xxx/0:
Adaptec AIC7xxx driver version: 4.1.1/3.2.1
Compile Options:
AIC7XXX_RESET_DELAY : 15
AIC7XXX_CMDS_PER_LUN : 8
AIC7XXX_TAGGED_QUEUEING: Enabled
AIC7XXX_PAGE_ENABLE : Enabled
AIC7XXX_PROC_STATS : Disabled
Adapter Configuration:
SCSI Adapter: Adaptec AHA-294X Ultra SCSI host adapter
(AIC-788x chipset)
Host Bus: Single
Base IO: 0x8000
Base IO Memory: 0xe4000000
IRQ: 11
SCBs: Used 8, HW 16, Page 255
Interrupts: 27717
Serial EEPROM: True
Extended Translation: Enabled
SCSI Bus Reset: Enabled
Ultra SCSI: Disabled
Disconnect Enable Flags: 0xff

I am plagued with lockups of the system anyway, they occur every few days
without SMP and within a few hours with SMP. The systems hangs with no messages
around, as far as I can see.
I tend to blame the SCSI adapter for that, because I have 3 more machines with
(almost) the same hardware, but they say
Adaptec AHA-2940 AU BIOS v 1.30
and are stable (even under SMP) for several months.
I tried kernel 2.1.72 + SMP on the unstable machines, with a strange result:
it locked cpu0 and continued to run on cpu1. This also survived a reboot,
I had to press the reset button to get cpu0 back to work...
Any ideas about further diagnostics and possible fixes are welcome
(and badly needed)!
