Not yet, I'm adding it in this afternoon.  I did the upgrade to Fedora
14 (and thus 2.6.35.10) and seem to be getting, if not the same bug, a
darned similar one:

I haven't added it to 20702 yet as I haven't had time to confirm if it's
the same issue, but at first glance it looks it.  My plan is to compile
up a mainline kernel, with the above patch, and with debugging turned on
and to capture as much as I can from that.
