To come back to this: my 3 systems (XFS filesystem) running the latest dm-crypt-scale-to-multiple-cpus patch from Andi Kleen/Milan Broz have not showed a single problem since 2.6.37-rc6 and above. No corruption any longer, no freezes, nothing. The patch applies cleanly to 2.6.37, too, and runs just fine. I blindly guess that my data corruption problem was related to something else in the 2.6.37-rc series up to -rc4/5. Since this patch is a significant improvement: any chance that it finally gets merged into mainline/stable?
