have tried merging driver from current, same affects...
Machine is running releng_4.
I am seeing the following messages (below). In my config, I
have:
options AHD_REG_PRETTY_PRINT
options AHD_DEBUG
options AHD_DEBUG_OPTS=0x1f
the 'test' is to do dd if=/dev/da0 of=/dev/null bs=20k
while letting other things run (in this case, tcpreplay,
but i suspect it doesn't matter).
The systems have a single seagate cheetah 15KRPM 18G drive,
as below:
# camcontrol inq 0:0:0
pass0: <SEAGATE ST318453LW 0004> Fixed Direct Access SCSI-3 device
pass0: Serial Number 3JY0A97X000073370XXA
pass0: 320.000MB/s transfers (160.000MHz, offset 63, 16bit), Tagged Queueing
Enabled
Interestingly, a set of otherwise equal systems with the U160 version
of this drive:
# camcontrol inq 0:0:0
pass0: <SEAGATE ST318452LW 0004> Fixed Direct Access SCSI-3 device
(pass0:ahd0:0:0:0): Handled Residual of 231 bytes
pass0: Serial Number 3EV02CLF00007236P39P
pass0: 160.000MB/s transfers (80.000MHz, offset 63, 16bit), Tagged Queueing
Enabled
do not have any problems with this same kernel. Dropping the speed to
160 on the problem systems does not affect the behaviour: they still crash.
(ie the ST318452LW works, the ST318453LW does not).
Once the messages below come out, i lose access to the drive (files
don't exist etc). If I reboot, the drive is no longer present on the
scsi chain, I must power cycle the device. This is very surprising to
me. I even tried hitting the reset jumper on the motherboard, same
affect, when in the 'bad' state, the drive must be power cycled to
restore.
System is supermicro x5dpr-8g2+ motherboard, which has onboard
AIC7902. I have two different revs of these (0x005f9005, and
0x005e9005). It doesn't seem to matter which of these rev of chips
I am using.
I would appreciate any suggestions on how to proceed.
Messages follow.
