This discussion on Linux-kernel moved to this list as it seems to involve
AHA2940UW and aic7xxx.c as a central thread. I have had persistent crashs
with my 2940UW's. Too bad, as the attached file shows, in my system the
2940UW are fast.

I carefully read and followed the recomendations of the SCSI3 spec for
cabling and termination. My cables are not over 1.5 meters, I have no
very short segments between the connectors. I terminate at the end of the
chain with the drives builtin terminators. I also explicitly set the
termination in the 2940UW. I also have tried other known good (and high
dollar) cables and have gotten the same results as my common sense
inexpensive cables. It ain't my cables.
As for my setup, I have three adapters (Asus PCI-sc875 is the adapter du
jour) and each adapter has three IBM DORS32160UW drives. I have
configured all nine disks as a raid0 (several partitions). Using initial
ram disk support, I mount my root file system on this raid0.
Here is my mdadd and mdrun.
/sbin/mdadd /dev/md0 /dev/sdb2 /dev/sde2 /dev/sdh2 \
/dev/sdc2 /dev/sdf2 /dev/sdi2 \
/dev/sdd2 /dev/sdg2 /dev/sdj2
/sbin/mdrun -p0 -c64k /dev/md0
With the BusLogic BT-958 and the Asus CPI-SC875, I have no problems; so
far I have run over 128 consecutive passes of Bonnie on files of 1GB or
larger on both adapters and no problems. I have really pounded the Hades
out of my disks with the BT-958, I have not tested the Asus quite so well
but the 2940UWs die miserably within about 3 or fewer consecutive passes
of bonnie on files of 2G size. The Asus handles the 2G files with aplomb
(though I have only done about 16 passes, it takes a while and I get bored
easily). Then the 2940 dies, a power cycle is required to restart.
Since two other adapters work perfectly, I am unconvinced that it is
my cables or my disks. Following are the non-commented configuration
details for my scsi drivers, I included all that I have used (and build
modules for) as a point of comparison.
CONFIG_SCSI_AHA1542=m
CONFIG_SCSI_AIC7XXX=m
CONFIG_AIC7XXX_TAGGED_QUEUEING=y
CONFIG_AIC7XXX_CMDS_PER_LUN=16
CONFIG_AIC7XXX_PAGE_ENABLE=y
CONFIG_AIC7XXX_RESET_DELAY=15
CONFIG_SCSI_BUSLOGIC=m
CONFIG_SCSI_OMIT_FLASHPOINT=y
CONFIG_SCSI_NCR53C8XX=m
CONFIG_SCSI_NCR53C8XX_TAGGED_QUEUE=y
CONFIG_SCSI_NCR53C8XX_MAX_TAGS=12
CONFIG_SCSI_NCR53C8XX_SYNC=20
CONFIG_SCSI_NCR53C8XX_SYMBIOS_COMPAT=y
I boot from the 1542 scsi and have no IDE or other boot media whatsoever.
Note that the scsi drivers above are all modules. Interesting eh?
/* One annoyance, Because /var is on the md0 raid, when I get a fatal
oops, I don't get anything in syslog. I once had /var/log on a different
file system though it didn't help, I still got no oops messages for scsi
driver barfs. I get oops messages for other things, I think that not
getting scsi oops messages is a consequence of the root file system mount
point. */
