[Regression/Oops] nsc-ircc: 4.3.0rc6/rc7 No backlight on Thinkpad T60P
From: Simon Wood
Date: Tue Oct 27 2015 - 11:08:09 EST
Tried the latest kernel and have the issue where the LCD backlight does
not light (ie dark screen) after the kernel has booted.
It appears that there is a 'oops' with the nsc-ircc driver, and I assume
that this is the root of the problem. 4.3.0rc6 and rc7 are bad, rc2 seems
OK.
