[GIT BISECT] kernel early crash in 2.6.34~2.6.35-rc1

Hello there,

I have individuated a bad commit which causes an early crash in some SSB/CPI routine; sorry can't be more precise right now, it would require serial debugging to get the dump.

Last good commit: 240ed68eb567d80dd6bab739341999a5ab0ad55d
First bad commit: 6e4513972a5ad28517477d21f301a02ac7a0df76

Hardware: laptop Maxdata PRO 7000DX (apparently Fujitsu Amilo V2000 clone)

Crash is also present in HEAD (currently 67a3e12b05e055c0415c556a315a3d3eb637e29e).

I have given a look to the commitdiff but it looks too much complex for me to individuate where's the issue at first glance.

Can somebody please give a look and/or narrow it down to a patch?

Thanks,

% git log 240ed68..6e451397 | grep -c '^commit'
6609

There are over 6000 commits in there - are you sure you cannot narrow it
down a bit more with git-bisect?

Sorry, I have had a bad day with git; the bug was in commit d53cdbb94a52a920d5420ed64d986c3523a56743 and is fixed by commit da1fdb02d9200ff28b6f3a380d21930335fe5429, so it's not affecting stable or either any other repository (perhaps drm-intel only).

By the way, it was at EIP ssb_is_sprom_available+0x40.

Best regards,

Yeah, we all have those sometimes ... and wish we hadn't got out of bed in
the morning...

Glad you found a resolution.
