Since some people have gotten back to me telling me that they have apparently been able to boot with the patch, I have a suspicion that it could be something in your config files. The other submitter already sent me his, so can you please send me yours (along with a 'dmesg' when you boot with a clean -current, without the patch) so that I can try building something similar here to hopefully track this down? (send them off-list, please) If anyone else is seeing something similar, also please send me your kernel config files with stock -current 'dmesg' output off-list.
