Created attachment 1938 [details] dmesg from the same system after power cycling Помогло (прямщас) poweroff вместо reboot (обновлялся с alt5) -- при повторной загрузке не вылезло "Disabling IRQ 11" при Populating /dev, oops не видно, мышка бегает, а не ползает...
На 2.6.18-std-smp-alt8 будто не наблюдается -- закрываю как WORKSFORME. (ThinkPad A30p)
