Already uncovered and fixed a few bugs in v3.
Here's v4 of the sata_mv new-EH patch.
you asked for test results with 2.6.21.3 ... that seems to boot fine,
and i've tested reading from the disks only and it seems to be working
fine. ditto for 2.6.22-rc3.
but 2.6.22-rc3 + your v4 patch fails... i'll send you the serial console
outputs offline.
Well, I have the same hardware as dean, and do not see the
BUG_ON/WARN_ON traces that he sees. These are the same two code
locations that caused spewage before. This only difference I see is
that he is testing with an NCQ-capable disk, and I am not -- which could
be a very significant difference. Dave also appears to have an
NCQ-capable disk.
Dave's output (sent privately to me) was different -- errors and
corruption -- rather than the BUG_ON/WARN_ON stuff both he and dean sent
in March 2007, which is interesting.
Dave, any chance you could try 2.6.22-rc3 + my v4 patch, on a different
hard drive? Preferably a non-Maxtor, or at least not another Maxtor
6L200S0. If that's a big deal, don't worry about it. I just want to
rule out buggy firmware and/or bad hard drive in your case.
dean's output (backtraces matching March 2007 reports) was what I
expected, and if I can reproduce that with an NCQ-capable disk locally,
I should be able to fix it from there without trouble. Probably just
some hardware bits accidentally kicking into NCQ mode, when they should not.
