Hello,
Since 2.4.18, we have a problem with the above combo if and only
if the transfer is odd number of bytes. Even byte transfer works
well. The error message we see is:
Sep 25 17:45:48 x kernel: st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
Sep 25 17:45:49 x kernel: sym0:0:0:extraneous data discarded.
Sep 25 17:45:49 x kernel: sym0:0:0:ODD transfer in DATA OUT phase.
Sep 25 17:45:49 x kernel: sym0:0:0:COMMAND FAILED (87 0 9).
I'm out of ideas what to try next, debugging didn't show up
anything unusual. The same hardware works with 2.2.19.
Any ideas?
Peter

And IIRC someone has made changes or at least put forth a patch to attempt to aleviate the odd byte count problem . It is in (Again IIRC) both of the Symbois drivers (ie: 53c8xx.c & sym53c8xx_2) . Do try a newer kernel than 2.4.21 tho 2.4.22 is what I am running . Hth , JimL -- +------------------------------------------------------------------+ | James W.

Yes, this is an old problem that keeps coming up. See: http://marc.theaimsgroup.com/?t=101018223200001&r=1&w=2 http://marc.theaimsgroup.com/?t=106074664100005&r=1&w=2 I have not seen any patch to fix it. My minor change in 2.4.22 was for the Ignore Wide Residue message on a Request Sense command, but that was a different issue. Anthony J.
