Comment (by jstressman):

 I blacklisted the cpuidle module in add-ons/kernel/power/cpuidle and this
 problem (along with my boot problem in #11020) disappeared.

 While the cpu usage is higher than it was before hrev46690, it's perfectly
 usable and barely noticeable compared to this bug's behavior.

 Attaching a screenshot from hrev48579 while running with cpuidle
 blacklisted to compare with the hrev48579 above without it blacklisted.
