commit 92eb1adbf8eced368f72df35deb01bb4d2e7bf85 Author: Vladimir Serbinenko phcoder@gmail.com Date: Sun Jan 5 00:51:12 2014 +0100
X230: current tree as-is.
Known issues: - No keyboard backlight (thinklight works) - No S3 - EHCI output sometimes get "stuck" until key is pressed after sysagent execution. - no S3 - MRC fails if MRC cache is supplied. For now MRC cache is disabled. - MRC sometimes hangs with message: System Agent: Initializing PCH {433e0f9f-05ae-410a-a0c3-bf298ecb2
So a watchdog is reenabled to reboot if this happens
Not tested: - ultranav - fingerprint - dock
