!!! Unknown header type 7f
Kernel driver in use: ahci
But from hexr, this device doesn't show up in 10.10 and 11.04 instances
of this same machine.
Also, from Lenovo's BIOS release notes for SL410
(http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/6juj20uc.txt),
it mentions:
Version 1.46 (BIOS ID: 6JET88WW) [for BIOS ID 6Jxxxxxx-based computer]
------------------------------------------------------------------------
[Problem fixes]
- Fixed an issue that might fail to go into standby/sleep state or resume normal
operation from standby/sleep state.
I think it's worthwhile to upgrade the BIOS to this version and re-test.
