Comment 50 for bug 204996

I think I have the same problem. For me it doesn't seem to be related to anything, although i usually have firefox open when it happens. That and tvtime. Sometimes it will completely lock up and if i dont click anything or touch the keyboard, it will come back in a few minutes. But once it comes back, if i do literally anything that would make it read the hard drive, it freezes permanently. I can use apps that are already open as long as they don't have to read the hard drive. I've tried alt crtl backspace, alt ctrl f1, and even alt sysreq R-E-I-S-U-B, at both lock ups. If i do it with the first lock up, it makes things worse and never comes back. If i do it with the second lock up, it either does nothing or it cause everything to freeze permanently. Just from it happening to me about 30 times (I've tried various things to fix it), I think it has to do with not being able to read the hard disk, or the kernel decides that it doesn't want to read the disk anymore. Also, sometimes it will come back after the first lock up and i try to open an app, an error message pops up saying something about being unable to load app because of an I/O error. But then it usually permenantly locks up after that. This problem has made me attempt to go back to 7.10 (although i'm having huge problems with grub). I really hope this bug gets fixed (even if it's not the same as mine).
