Hi Matthew,

I trust that you could advise me about this pb:

on my b2k since I can run 2.6 (32bit with gcc-3.3 or 64bit with gcc-3.0)
i noticed from time to time such dmesg:
sym0:5:0: ABORT operation timed-out.
sym0:5:0: ABORT operation started.

sym0:5:0: ABORT operation timed-out.
sym0:5:0: ABORT operation started.

sym0:5:0: DEVICE RESET operation timed-out.
sym0:5:0: BUS RESET operation started.
sym0: SCSI BUS reset detected.
sym0: SCSI BUS has been reset.
sym0:5:0: BUS RESET operation complete.

and during this time the system naturaly hang.

scsi id 5 is the one of the working boot disk (a quantum model atlas5-9lvd)
and if there is well a second disk (a seagate model ST336704LC) it is not
used.

OTC with 2.4 and sym2 driver, I never noticed this behavior (even with recent
2.4.25-rc?-pa0 :) ), so I presume that there is no disk failure (and a dd
if=/dev/sda of=/dev/null bs=1024k reach to read fully the disk without any
error).

Any idea?

Thanks in advance,
    Joel

Hello Grant,

Typicaly the behaviour observed.

In fact according <http://www.seagate.com/cgi-bin/view.cgi?/scsi/st336704.lw>
it has the two possiblity SE or LVD according HW config (a side jumper J2
if i well understand)

But here they seems to work together in LVD mode:

Anyway what sym2 look for at scsi id 0?

I will try also later to remove ST disk ad advise ;)

Thanks for attention and advise,
    Joel
