> I've been using a kernel which is between 2.6.37-rc2 and -rc3 with a LUKS / dm-crypt / LVM / ext4 setup for my primary file systems, and I haven't observed any corruption for the last two weeks or so. It's on my todo list to upgrade to top of Linus's tree, but perhaps this is a useful data point.
The reported corruptions are with a .37 forward port someone did of my parallel
kcryptd patch. The 2.6.36 (and earlier) versions are rock solid with many users.
The classic dmcrypt is single threaded and very slow.

A compiler problem seems very unlikely here.
What may be an useful experiment would be to test 2.6.37-rc + ext4 over
device mapper, but not dmcrypt. If that fails too then it's likely
some generic device mapper problem.
