На ядре версии 3.0.7 без нареканий работал режим hibernate.

После обновления до 3.0.13-std-pae-alt0.M60P.1 при переходе в спящий режим с большой вероятностью (в смысле, иногда работает) происходит подвисание. Если добавить no_console_suspend, то наблюдается следующее:

rcu_sched_state detected stalls on CPUs/tasks: { 1} (detected by 0, t=15002 jiffies)
No irq handler for vector (irq -1)

Пробовал как с видеодрайвером nvidia, так и с nouveau. Стабильно повторяется на нескольких машинах с одинаковым железом.
