Присоединяюсь. Нетбук DNS с Intel Atom N2800 на борту, вывод lspci -v опередил комментарий. С ядром 3.6.2-un-def-alt1 при втыкании SD-карты ничего не происходит.

Ping. Я думаю, собака зарыта где-то в наших патчах, т.к. с текущими ядрами изменений нет. С un-def кардридер _не_ виден. С std-def все нормально. Да, кардридер PCI, не USB.
Сломали и в std-def! Blocker'ом тогда будет.

Все равно продолжает не работать. Таки нашел то, ЧТО нужно искать. Сделал CONFIG_REGULATOR_DUMMY is not set и взлетело. Причем в 3.6.11-std-def оно было выключено. Ссылка по теме http://www.spinics.net/lists/linux-mmc/msg18259.html
Повторяю, между 3.6.11-std-def-alt1 и 3.7.7-std-def-alt1 был включен CONFIG_REGULATOR_DUMMY: --- config-3.6.11-std-def-alt1 2012-12-18 14:39:48.000000000 +0400 +++ config-3.7.7-std-def-alt1 2013-02-11 22:46:09.000000000 +0400 -# CONFIG_REGULATOR_DUMMY is not set +CONFIG_REGULATOR_DUMMY=y В результате кардридер, описанный выше, обслуживаемый модулем sdhci_pci не работает, не реагирует на вставку карты.

После возвращения в конфиг ядра # CONFIG_REGULATOR_DUMMY is not set и пересборки кардидер начал работать.
