Now that I've seen this a bunch of times, I can confirm:
- ssh always continues to work! I must have made a mistake early on when I thought it didn't.
- freezes occur in GNOME, GNOME safe mode, xterm sessions, and even once at the gdm login prompt (but this was after a GNOME session and a logout).
Also, sometimes I seem to be able to induce the freeze by switching between virtual terminals and X with ctrl-alt-F?, but not always.
Please let me know if any more information or investigation would be useful. This is a high-priority bug for me as it makes my main machine unusable.
