Ok, bisect found this commit as the faulty one: put stricter guards on queue dead checks
2.6.38.8 has a bug fix for this specific commit, but as you tested on comment #10 it seems you still have the problem even with 2.6.38.8, so another fix probably is required. Just to confirm, I'll cherry-pick the fix from 2.6.38.8 and ask you to test a kernel with it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/793796 Title: 2.6.38-10 panic after ejecting drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/793796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
