There is a bit progress, you can read the details at http://www.linux- archive.org/device-mapper-development/474248-problem-ssd-access-time-dm- crypt-way-too-high.html. There are currently two patches, which completely resolve the issue for me, but have their own problems and presumably won't go into mainline.
There is also a bugreport about similar issues on the kernel bugzilla (https://bugzilla.kernel.org/show_bug.cgi?id=17892), but since the issues persist with 2.6.32, it could be another problem. ** Bug watch added: Linux Kernel Bug Tracker #17892 http://bugzilla.kernel.org/show_bug.cgi?id=17892 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/653611 Title: extremely bad dm-crypt latency -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
