I've checked the bug list for the 10.10 and found that this bug is similar to the #634702 bug. So I've rebooted the 2.6.35-28 kernel with the "intel_idle.max_cstate=0" parameter on the command line and everything went fine. My PC is based on an Asus P6T (X58 Chipset) with a CoreI7 CPU. But because my system is overclocked, I have disabled all the power/frequency control function in the BIOS: C1E Support, SpeedStep Tech and C-State Tech are disabled to be sure that the CPU frequency is as stable as possible. When I boot without the parameter on the command line, I have the following report from the intel_idle driver in dmesg: [ 2.050129] intel_idle: MWAIT substates: 0x1120 [ 2.050130] intel_idle: v0.4 model 0x1A [ 2.050131] intel_idle: lapic_timer_reliable_states 0x2 [ 2.053740] ACPI: acpi_idle yielding to intel_idle So, the driver is loaded and runs even if C-State is disabled in the bios ! It could be the cause of the kernel crash.
