(but I guess a patch > from 2007 won't apply cleanly ...) bio_split is called from linear_make_request, which is MD raid code. (MD linear is very rarely used IMHO, device-mapper & LVM usually works better in this situation - can you try to reproduce it using DM?) Anyway, seems like and MD bug, please forward it to md list linux-raid@vger.kernel.org (please cc me, if it uncovers some bug in dmcrypt, I'll fix it) Milan p.s. > After talking to the btrfs devs on freenode (as btrfs is the most > experimental thing in the stack, they came to the conclusion > that it's most probably the crypto layer. They are repeating this for years every time they see dmcrypt in stack despite they are not able to provide reliable reproducer. We have no such report for ext3, ext4, xfs or any other fs.
