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: http://pastebin.osuosl.org/36644 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. - John 'Warthog9' Hawley
