Revision 4dea5806d332f91d640d99943db99a5539e832c3 authored by Yinghai Lu on 19 September 2013, 04:05:20 UTC, committed by Rafael J. Wysocki on 19 September 2013, 22:37:10 UTC
On systems that support intel_pstate, acpi_cpufreq fails to load, and udev keeps trying until trace gets filled up and kernel crashes. The root cause is driver return ret from cpufreq_register_driver(), because when some other driver takes over before, it will return EBUSY and then udev will keep trying ... cpufreq_register_driver() should return EEXIST instead so that the system can boot without appending intel_pstate=disable and still use intel_pstate.
