The crash appears to be due to either the scsi or block code.

The problem with the crashs after booting which started with 2.6.39-rc1 continues with 2.6.39-rc3-git3
Pls see enclosed a screen foto
Pls see below also a comparison of the config between
2.6.38.2 , what don't crashs but runs stable. Thus, the
problem are either the general changes from 2.6.38.2 to 2.6.39, or one of the few additional features visible from the diff below.

It's a bit hard to tell from the jpg, but it looks like it could be another instance of the steve whitehouse crash that was discovered a day or so ago. We're still preparing the final fix, but this is what we have as an interim if you could try it out.

It's just code motion, so it was cut and paste. The actual file is a nasty mix of comment styles, so it doesn't really matter one way or the other.

It's just code motion, so it was cut and paste. The actual file is a nasty mix of comment styles, so it doesn't really matter one way or the other.

That's not really true - most other multi-line comments are fine in that file - i checked that before sending my feedback.

Really, why are you even arguing about it? You have not noticed it during review - that can happen - but you should really fix small details if someone points them out during review. Instead you are forcing reviewers though an unnecessary and time-wasting email exchange.

Thanks,

The problem with the crashs after booting which started with 2.6.39-rc1 continues with 2.6.39-rc3-git3

Although I'm not sure whether it is related, another bug report about a lockup introduced between 2.6.38 and 2.6.39-rc1 can be found here:
