It doesn't panic anymore, but it says `Device on port is bricked'.
Increasing the timeout in ahci_poll() command on line 145 doesn't help
(same console message).
By the way the controller is JMB360 from JMicron, and I found a very
old patch against linux kernel:
  http://lkml.org/lkml/2006/1/29/2

but the driver has been quite reorganized since then, so I have no idea
how this patch fits in our ahci driver.
