[SOLVED] выход из suspend

Доброго времени суток. После масштабного обновления системы на нетбуке начались проблемы с suspend'ом. Уходит машина в него нормально, а вот возвращается с задержкой ~200 секунд, если верить логам. Вот dmesg, и pm-suspend.log.
Смущают вот эти строчки в dmesg:

[  127.378610] ACPI: Waking up from system sleep state S3
[  127.386588] ACPI Warning: For \_WAK: Return Package is too small - found 1 elements, expected 2 (20120913/nspredef-679)

[  334.041093] ehci_hcd 0000:00:1d.7: wake-up capability disabled by ACPI

это после первого ухода в suspend. Если после выхода отправить еще раз получаем:

В ядре вроде все включено. Гуглинг ничего внятного не дал. Может кто-нибудь сказать, куда посмотреть?

UPD: после пары пересборок ядра в /var/log/messages начало падать
