I saw a kernel crash in maverick RC testing. I will attach console output here, the system reported is the same AMI, but the issue occurred on c1.xlarge instance type.

SRU Justification:
Impact: Booting an Intel based instance with certain CPU level will fail with a panic as the driver does not seem to take into account that it is running in a virtualized environment. This only is a problem with the intel_idle driver.
Fix: Turning off intel_idle driver support for the virtual kernel image will let it use the generic idle driver as before. As this option is only changed for the virtual kernel package there is no risk of regression for the generic packages.
Testcase: Booting a large instance (with 68GB of memory) very likely results in this panic as the memory size will result in selecting certain base hardware with Intel CPUs. Turning the option off lets those instances boot again.
