List,
This used to work with an older SUSE install...(!)... Now I'm
using Slackware... With an Adaptec 2940 UW Pro, attached to a Sony
SDT-10000 tape drive, the Kernel panics with a 2.4.12 or 2.4.13 kernel
with _either_ the standard aic7xxx _or_ the aic7xxx_old drivers in the
kernel bundle.
BUT, this only happens after 2 minutes of a tape backup, at
almostthe same exact place in the backup each time. I thought it was
tapes, nope.
Precisely:
Kernel panic: aic7xxx: unrecoverabl BRKADRINT
In interupt handler - not syncing
..funny thing, though.. while the backup is rolling along
initially, the 'busy' light blinks slowly as expected.. Once the backup
'locks', the blinking is rapid, even and continuous..
aic7xxx_old:
CONFIG_SCSI_AIC7XXX_OLD=y
CONFIG_AIC7XXX_OLD_TCQ_ON_BY_DEFAULT=y
CONFIG_AIC7XXX_OLD_CMDS_PER_DEVICE=8
CONFIG_AIC7XXX_OLD_PROC_STATS=y
aic7xxx:
CONFIG_SCSI_AIC7XXX=y
CONFIG_AIC7XXX_CMDS_PER_DEVICE=253
CONFIG_AIC7XXX_RESET_DELAY_MS=15000
I see many posts saying that older drivers worked(?).. How
far back do we have to go to get a working driver?
AND I even tried with (what I'm running now):
Linux atcp 2.4.12 #1 SMP Sun Oct 28 17:44:05 EST 2001 i686 unknown
and patch:
linux-aic7xxx-6.2.4-2.4.12.patch
from dmesg:

Ideas?
