thanks Brian, looks like my kernel headers and image are updated (not sure about restricted modules, is that relevant?).
I am attaching little info from my laptop (DELL 600m Celeron 1.5Ghz). My ultimate problem of processor persistance in high C2 power state remains. With 2.6.12 kernel I have frequent C3 and C4 states, with current 2.6.15-26.46 - very low. -- cpu idle time in /proc/stat wrong https://launchpad.net/bugs/30557 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
