Comment 33 for bug 870326

hi,

i am having this problem after installing 11.10 amd64
after reinstalling 11.10 and re-using existing encrypted home partition i find these entries on my /var/log/kern.log

could you tell me what info you require to investigate this?
this problem is really worrying since it may imply that i could have my private data corrupted.
