Description Caleb Crome 2009-07-16 09:21:04 UTC

I got a kernel oops when I was testing the power button.

* I stopped the jive app
* ran evtest /dev/input/event1
* pressed a bunch of times.
* went to a meeting
* came back 10 minutes later
* and pressed the power button.

I got the following oops.  Probably pretty minor, but filing just in case it's indicitive of some underlying problem:

Comment 1 Richard Titmuss 2009-07-24 02:42:30 UTC

This is a bug in the freescale backlight driver, caused by stopping jive for a prolonged time. Nothing to do with pressing power. Won't fix, it's not important.
