Public bug reported: Natty Beta 2 on a Lenovo Thinkpad T420s, packages up to date. While copying data form another harddrive or via rsync, I get errors leading sometimes to the filesystem being remounted read-only and others to kernel panic (complete with CAPS LOCK blinking). This makes the computer unusable and I think I risk losing data (luckily have backups).
Tested in console to make sure it was not video problem, go a lot of kernel debug messages printed on the terminal but they do not stay in /var/log (since by the time the error is hit the filesystem is read only, I guess). I will be glad to provide any further necessary information.
