Subject: -tip: origin tree boot crash
Today's -tip crashes during bootup (x86 allyesconfig, 64-bit), due to this
commit from yesterday's upstream -git tree:
commit a328e95b82c1b8483ae5ab2f809140664d7f6c92
Author: Dave Hansen <dave@...1.net>
Date: Thu Oct 1 15:43:32 2009 -0700
leds: LED driver for Intel NAS SS4200 series (v5)
The crash serial log is attached below. I suspect this driver was not booted
on hardware that does not have that LED interface?
Thanks,
Ingo
