The following patch fixes the problem for me. Do we want to accept this
patch and call it a day or continue investigating the source of the problem?
Patch applies to 2.6.24.2, but doesn't apply to 2.6.25-rc. If everyone
agrees that this is the right solution, I will resubmit with a proper
subject line and description.
