| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It appears that when powernow-k8 finds that No compatible ACPI _PSS objects found. and suggests Try again with latest BIOS. it fails the module load, but does not unregister the cpu_notifier that was registered in powernowk8_init This ends up leaving freed memory on the cpu notifier list for some other poor module (e.g. md/raid5) to come along and trip over. The following might be a partial fix, but I suspect there is probably other clean-up that is needed. ( https://bugzilla.novell.com/show_bug.cgi?id=655215 has full dmesg traces).

| | | | | | | | | | | | | | | | | | | | | | | | Just as we had to disable auto-demotion for NHM/WSM, we need to do the same for Atom (Lincroft version).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware C-state auto-demotion is a mechanism where the HW overrides the OS C-state request, instead demoting to a shallower state, which is less expensive, but saves less power. Modern Linux should generally get exactly the states it requests. In particular, when a CPU is taken off-line, it must not be demoted, else it can prevent the entire package from reaching deep C-states. https://bugzilla.kernel.org/show_bug.cgi?id=25252 Signed-off-by: Len Brown <len.brown@intel.com>

However, the value passed to _dpll_test_fint() is already "N+1" since Linux is using the values to divide by. In the technical reference manual, "N" is referring to the divider's register value (0-127). During power management testing, it was observed that programming the wrong jitter correction value can cause the system to become unstable and eventually crash.

This code-path does not advance the guest-rip causing the guest to dead-loop over mov-dr instructions. This is fixed by this patch.
