Patch applies fine to vanilla 2.6.29, after removing a little from the
non code part of your email ... :) .. And after some ugly debate with
mutt here because it first changed the code when saving the patch:
I had to save the message as an attachment, and not from the usual
read view on that message, IINM ... worked in the end tho ... :)

I don't have the sources anymore for my current kernel, so I will
try build a kernel from that stable 2.6.29 lying around ... 

Feedback on whether the patch helps can take many weeks - because the
described bug usually shows up only every 2 months or so ...

Anyways - thanks a lot your help

Nice weekend

Best Regards
