I also experienced the exact symptoms of the bug, combined with a bunch
of other problems (sound crackling, system freezes).

This workaround fixed it all together for me (ubuntu 10.04, 2.6.32-36-generic):

 in /etc/default/grub change line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to be

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash clocksource=jiffies"

Then enter sudo update-grub and reboot. See if your problems are gone.

Unfortunately that triggered another bug: hd-audio0 eats up 20% of my
cpu, but that's another story.
