It went bonkers again. This is with 2.6.25. I'll build 2.6.26-git and try again with that shortly. One thing about sata_sil24 --> it *really* doesn't like to handle hotplug events while in the midst of EH. I unplugged the host cable from the PM, and the EH just kept on going and going. I then unplugged the sata_sil24 PCIe host adapter card, and it still took quite some time to give up on the Energizer Bunny routine. :) Anyway, this is my main machine, so I'll be out for a spell now while rebuilding/rebooting.
