I had the exact symptoms as John described in the initial bug-report.
After I read the post at http://ubuntuforums.org/showthread.php?t=251944 I removed my rt61 WLAN card, rebooted with the Herd 5 Live CD, and now my computer no longer freezes!
This means the problem is probably related to the rt2x00 package, which explains why this problem is not present in Edgy.
