Sorry, it was not meant to be rude or anything... more frustration since I cannot be of more help and I really would like to jump in head-first and help fixing it... but lack the necessary insight into the kernel internals.

I have to read those more closely tomorrow, since there are some nice insights into dm-crypt there. :) Still, you have to admit, it is also rather frustrating/scary if such a crucial subsystem can have bugs over several major versions that do result in complete hangs (and can thus cause corruption) and are quite easily triggerable. It does not instill too much confidence that said subsystem is so intensively used/tested after all. That's at least how I feel about it... So long, Matthias -- Dipl.-Inf.
