Hmm.. my IBM TP X31 running 2/27's current, I saw some

ad0: READ_DMA timeout (retry 2 left) LBA=....

and it hangs, hdd's light is on. I have to press power button to turn off it.
Strangely, after resume, it is alive for about 2 seconds before
that message. Anyway, I don't have apic in kernel conf.
