Сабж. slackware 13.37/2.6.37.6. Прямо на ровном месте могут отпасть устройства (мышь и внешний жесткий диск) После перезагрузки все нормально. Баг вроде встречается на убунтовском ланчпаде, но фикса я не увидел. Вопрос, собственно, в том (если лор не поможет пофиксить), как без перезагрузки с этим справиться. А то патрег вон писал, что мы не перезагружаемся по сто раз, а тут такое :( Пишут, что this is a kernel bug. Кстати, тачпад остается работать.
Простите за простыни.
