Comment 18 for bug 638434

Actually I also spoke too soon. There are still freezes. The machine seems to boot fine but often won't shutdown without keypresses to help it along. Also the sound regularly gets stuck in a loop unless you keep up constant activity like moving the mouse.

I tried the kernel build in bug 634702 (comment #27) but it doesn't help on my Toshiba hardware. (I had hoped it would since they are both N450 NM10 style machines).

So as far as I'm concerned this is still an outstanding issue.
