Hi Bo,
Can you post your .config?

Interesting. I encountered a similar issue on a Lenovo laptop and has been fixed by the patch which mentioned
in http://marc.info/?l=linux-acpi&m=137568804802772&w=2. So I thought latest vanilla kernel tree should contains the patch.

Hi ...
Now that my X1C are working I am quite happy about it, and now I
am looking at the details.
When I boot the laptop (Debian Jessie + 3.14rc7 + Shuduo's patch)
I end up in a blank screen, the only way to get anywhere is to
suspend it and resume, and then i have a beautiful login screen,
and the laptop works nicely until next reboot.
In the dmesg i get the following remarks :
[ 1.605320] thinkpad_acpi: ThinkPad BIOS GRET32WW (1.09 ), EC
unknown
[ 1.605322] thinkpad_acpi: Lenovo ThinkPad X1 Carbon 2nd, model
20A7005LMD
[ 1.607060] thinkpad_acpi: Unsupported brightness interface,
please contact ibm-acpi-devel@lists.sourceforge.net<mailto:ibm-acpi-devel@lists.sourceforge.net>
[ 1.607142] thinkpad_acpi: unknown version of the HKEY
interface: 0x200
[ 1.607198] thinkpad_acpi: please report this to
ibm-acpi-devel@lists.sourceforge.net
I know the HKEY problem is worked on, but could the "brightness
interface" problem be related to the blank screen after boot problem ?
