description |
The symptom was the 'CPU Frequency Scaling Monitor' quitting, and when re-started, quitting again immediately.
Looking at dmesg there is a kernel NULL pointer dereference 'Oops' for every time 'CPU Frequency Scaling Monitor' died.
Linux shim 2.6.28-12-generic #43-Ubuntu SMP Fri May 1 19:31:32 UTC 2009 x86_64 GNU/Linux
I upgraded to the 'Ubuntu Proposed' 2.6.28-12 kernel from the standard 2.6.28-11 after experiencing daily GPU lock-ups, file system errors (auto remount read-only), and similar kernel Oops. This laptop was a rock-solid experience with Intrepid 8.10 but is sadly an unstable mess since upgrading to the Jaunty kernel and Jaunty Intel video driver. Wish there was an easy way to go back to 8.10!

A range of kernel 'Oops' and eventually file system-failure crashes that seem to involve 'sysfs'.
One symptom was the 'CPU Frequency Scaling Monitor' quitting, and when re-started, quitting again immediately.
Looking at dmesg there is a kernel NULL pointer dereference 'Oops' for every time 'CPU Frequency Scaling Monitor' died.
