I am attempting to build a 2.4.8 kernel for use on a VA Linux
2230 system. The system, running the stock VA kernel, reports
itself as containing an "<Adaptec AIC-7896/7 Ultra2 SCSI host
adapter>".
I have been patching 2.4.8 with Justin Gibbs' patches from
http://people.freebsd.org/~gibbs/linux/, specifically the
6.2.4 patch for 2.4.8.
Now, I have yet to encounter a situation where using this
kernel (with everything compiled in - I'm kickstarting the
VA box with this kernel) _fails_ to generate the following
errors (in no particular order):
aic7xxx_abort returns 0x2002
aic7xxx_dev_reset returns 0x2002
scsi: device set offline - not ready or command retry failed
after bus reset host 1 channel 0 id 0 lun 0
>From looking thru the messages file on a second 2230 (they
were a pair), I see this:
(scsi0) <Adaptec AIC-7896/7 Ultra2 SCSI host adapter> found at PCI 0/12/0
(scsi0) Wide Channel A, SCSI ID=7, 32/255 SCBs
(scsi0) Downloading sequencer code... 395 instructions downloaded
(scsi1) <Adaptec AIC-7896/7 Ultra2 SCSI host adapter> found at PCI 0/12/1
(scsi1) Wide Channel B, SCSI ID=7, 32/255 SCBs
(scsi1) Downloading sequencer code... 395 instructions downloaded
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.1.27/3.2.4
<Adaptec AIC-7896/7 Ultra2 SCSI host adapter>
scsi1 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.1.27/3.2.4
<Adaptec AIC-7896/7 Ultra2 SCSI host adapter>
scsi : 2 hosts.
Which leads me to believe that there are 2 busses served by
this adapter. Correct, incorrect or otherwise?
There are 4 Seagate ST318404LW disks on the bus. The Adaptec
BIOS reads as a 7896 version 2.20S1B1.
I compiled a 2.4.8 kernel w/o the 6.2.4 driver and now I get
these errors:
aic7xxx_abort returns 8194
aic7xxx_dev_reset returns 8194
scsi: device set offline - not ready or command retry failed
after bus reset host 0 channel 0 id 0 lun 0
Apparently, its probing the bus incessantly since the target ID
keeps incrementing thru 15 then starts at 0 again. This behavior
has happened with both the 2.4.8+6.2.4 and stock 2.4.8 before
oopsing out. I can collect the oops data but I haven't as yet.
I have tried adjusting the TCQ per device to 128 and 64 (on
2.4.8+6.2.4) and to 128 and 8 on the stock 2.4.8 build.
So my ultimate question is is this kernel rev (2.4.8), with or
w/o the 6.2.4 driver, appropriate? Should I be looking at 2.4.12
or even an -ac release? What steps should I be taking in this
regard? Is there any other useful information I should provide
for this to make sense? What do these errors indicate?
Any and all advice accepted. This is killing me!
I receive the LKML digests from Dell but not individual submissions.
Direct replied are fine.
TIA!
