Does anyone know if upgrading to the latest kernel would help? I'm having the same problem on a Vaio Z750. It's a 64 bit, dual core with a fresh install of Jaunty (several fresh installs over the last few days). It locks up and and the leds flash. I can't do anything, even with REISUB or the off switch. The only way to get out is to unplug the laptop and remove the battery.
When I try to boot up again, this is the last and first things in the kernel log: May 25 15:48:08 l-laptop kernel: [ 324.288093] CE: hpet increasing min_delta_ns to 15000 nsec May 25 16:52:51 l-laptop kernel: [ 4207.164049] CE: hpet increasing min_delta_ns to 22500 nsec May 25 21:46:28 l-laptop kernel: Inspecting /boot/System.map-2.6.28-11-generic May 25 21:46:28 l-laptop kernel: Cannot find map file. Earlier (right after boot up), there's a: May 25 15:42:59 l-laptop kernel: [ 5.183767] Marking TSC unstable due to TSC halts in idle and a: May 25 15:42:59 l-laptop kernel: [ 6.501104] Clocksource tsc unstable (delta = -145986009 ns) Whether I can fix the partition with fsck or have to boot to the installation disk, my user directory is gone. Whether I go to a later or an earlier kernel, do I have to reinstall Ubunty, then change the kernel? A appreciate any help you can give me.
