I have been having exactly the same abrupt rebooting after compiling .13 with realtime patch (not yet working on PAM tweaks). I have googled for possible conflicts with predetermined Ubuntu Breezy kernel config; I would like to preserve as much original Ubuntu's functionality as I can (at least for experimental purposes). BTW 64Studio people has achieved .13 multimedia kernels; they do kernel tweaking like butter (as seen at their dev's mailing list). Are these guys using the Molnar + rt/PAM solution? (Sorry, just can't do a complete installation of 64Studio now.) thank you in advance, Jos?

MCE seems impossible to disable..although maybe this is dependent on some other checkbox somewhere else. is there an option somewhere for writing a dump to disk (maybe in /boot) on kernel panic? > > the nature of the auto-reboot reminds me of kernels compiled for ppc G5 and running on G3, or PIII running on a P60mhz.. > > carmen.. > > > > > Lee > A
