SSD firmware update seems to have solved the issue. Why it occurred only in recent weeks, I have no idea, though. I've been running 3.5.0-19-generic since my last update without issues after updating the SSD firmware.
If anything happens, I'll re-open and post more information. ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1082700 Title: Accessing disk fails (SSD) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1082700/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
