Hi.
I have an ASUS P2B-DS with two Quantum ATLAS 10K 9WLS scsi harddisks
attached (no other scsi devices attached.)
Kernel 2.2.14-smp (from redhat 6.2) works fine, but with kernel
2.4.0-test5/6 the driver cannot detect the harddisks correctly.
It enters a reset loop, and if it finds any scsi devices, their names
are usually wrong, and type id seems random (printer, scanner, etc.).
Using the bootparameter: aic7xxx=no_reset, helps, as the harddisk
usually (not always) are detected correctly, though timeouts still
occur. Below is a snip from the kernel log, using the no_reset
parameter.

Aug 7 15:58:37 lagoon kernel: SCSI device sda: hdwr sector= 512 bytes.
Sectors= 17938986 [8759 MB] [8.8 GB].
I've tried a number of combinations of other AIC7XXX boot parameters,
but nothing seems to do any difference.
I've also tried to remove the AIC7XXX_STRICT_PCI_SETUP definition, but
this did not help either.
Any suggenstions?
Btw.
the ASUS P2B-DS uses an daptec AIC-7890/1 controller. below the
/proc/pci
Bus 0, device 6, function 0:
SCSI storage controller: Adaptec AIC-7890/1 (rev 0).
Medium devsel. Fast back-to-back capable. BIST capable. IRQ 5.
Master Capable. Latency=32. Min Gnt=39.Max Lat=25.
I/O at 0xd000 [0xd001].
Non-prefetchable 64 bit memory at 0xe0000000 [0xe0000004].
And the scsi part of .config (the "# CONFIG_SCSI_XXX is not set" entries
is removed.)
