Hmm, bisection can sometimes lead us in the fields, nasty. Well, you could try bisecting the major releases in between. I.e., test 3.8-rc1, and then test vanilla 3.7. For example, if you still trigger it with -rc1, then no need to bisect the -rc2..-rc1 range. If you still trigger it with 3.7 then not good - in that case you'd need to go further back in time. The best would be if you don't trigger it with 3.7 but trigger it with 3.7.1 :) Then it is easy. Also, git bisect skip can skip ranges of commits. You could try that too but you need to visialize how exactly the tree structure is and I admit, I haven't figured out the details of that yet but Linus has explained this approach a couple of times, you might want to take a look at this http://www.yarchive.net/comp/linux/git_bisect.html or search the net for even better ideas. Also, you said "with 3.8.0-rc2 it looks like it's working correctly - I've tried the unplug/plug sequence more than 5 times and it seems to work fine." Please test that again and repeat that sequence say 15-20 times, to make sure that -rc2 is really ok and not something changed timing and this bug is being only brown-paper-baggy-covered now.

For example, if you still trigger it with -rc1, then no need to bisect the -rc2..-rc1 range. If you still trigger it with 3.7 then not good - in that case you'd need to go further back in time. The best would be if you don't trigger it with 3.7 but trigger it with 3.7.1 :) Then it is easy. Also, git bisect skip can skip ranges of commits. You could try that too but you need to visialize how exactly the tree structure is and I admit, I haven't figured out the details of that yet but Linus has explained this approach a couple of times, you might want to take a look at this http://www.yarchive.net/comp/linux/git_bisect.html or search the net for even better ideas. Also, you said with 3.8.0-rc2 it looks like it's working correctly - I've tried the unplug/plug sequence more than 5 times and it seems to work fine. Please test that again and repeat that sequence say 15-20 times, to make sure that -rc2 is really ok and not something changed timing and this bug is being only brown-paper-baggy-covered now. I mean, I'm just guessing - you're in front of the machine, you know best what to do to trigger the bug reliably. HTH. -- Regards/Gruss, Boris. Sent from a fat crate under my desk.

Bisecting between 3.7 and 3.8-rc2 (from linus tree) led me to commit 63e1ed2364050073770c085021377d7764969b85 titled Update vt8500 PWM driver support, which I think is rather nonsense. Also, depending on bisected version, sometimes I got kernel panic, but sometimes (more often) whole system would just freeze completely. Any other way diagnose this bug? Hmm, bisection can sometimes lead us in the fields, nasty. Well, you could try bisecting the major releases in between. I.e., test 3.8-rc1, and then test vanilla 3.7. For example, if you still trigger it with -rc1, then no need to bisect the -rc2..-rc1 range. If you still trigger it with 3.7 then not good - in that case you'd need to go further back in time. The best would be if you don't trigger it with 3.7 but trigger it with 3.7.1 :) Then it is easy. Life isn't easy :-) with 3.7 I can trigger it too, but I can't trigger it with 3.8-rc1, so the fix lies somewhere between 3.7.1..3.8-rc1. I'll try bisecting it again. Also, git bisect skip can skip ranges of commits.

Hmm, you could bisect the set between 3.7.1..3.8.0-rc2 to find out which one to backport. If you can still reproduce it reliably and have time for bisecting, that is :).
