Comment 10 for bug 665891

Hello Christopher,

The problem seem to have gone away when updating to the first 12.04 beta.
If I'll notice any more problem I'll add more information.

Thanks for make such a great release,

It seems to be a race condition related to Intel Idle Driver.  Using the boot GRUB parameter "intel_idle.max_cstate=0" which disables the new Intel Idle Driver and assures fallback to ACPI idle, the problem disappears.  Another, less clean, workaround was to completely disable Intel SpeedStep in BIOS.

Brief testing on 2.6.32, 2.6.33 and 2.6.34 kernels led to same resume freezes; on Lucid 2.6.32 kernel it *seemed* that disabling "/usr/lib/pm-utils/sleep.d/94cpufreq" script has helped to avoid the race condition on resume.
