Same problem here. Thinkpad X61. Computer freezes during high disk activity. Though, it's probably not EXT4, because I had the same problem with a EXT3/Reiserfs setup. In fact, I did a clean ext4 install to test out my original theory of this being a reiserfs problem.
Sometimes you can recover from the freeze by waiting a bit and gently tap the power button, which can bring up the Gnome shutdown panel. Even after recovery, computer quickly becomes unusable and loaded with some kind of processing. If you check powertop, you would find the processor mysteriously at C0 80 or 90% of the time with no program attributable to the activity. No weird messages or oops in kernel log. But I do have a theory about this being a problem with Ath5k. -- linux freezes completely since 2.6.28-7 https://bugs.launchpad.net/bugs/338645 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
