When I boot up my PC (duel boot with Vista, which works fine) and go to ubuntu in the grub menu I get an almost immediate kernel oops. Errors include (from memory)
The oops dumps a Call Trace which looks to be knee-deep in ext4 modules.
So I booted the normal desktop live CD for 10.10 and tried to mount the ext4 partition from there. All of the utilities which I used to try to access the partition failed to complete, they just hang. These include
mount on the command-line and the
Disk Utility found under the live CD's Administration menu.
The BIOS has a low-level scan which reported that the hard drive is physically OK. I confirmed this by successfully booting the Vista partition.
The other weird thing is that I didn't do anything to the machine while it was still working to prompt it not working anymore. No messing around with file systems, no partition resizing or anything risky at all. Was just using it the day before for watching movies.
Is there anything I can try to recover some of the files on there?
