Hi Seth,

One bad experience I have had since installing the patched kernel. After
countless good boots I decided to add the following lines to
/etc/tc.local in order to use switcheroo:

chown "username" /sys/kernel/debug/vgaswitcheroo/switch # change "username" with your user name
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

Everything seemed to work for the first 5 or so boots but then I started
getting the blackscreens again. The message was similar but not the
same. Unfortunately I didn't manage to get a screen of it.

Once I got back into my desktop I removed the lines from rc.local and
then the issue disappeared.

I've gone ahead and added the lines again to see if I can recreate the
issue but so far nothing.

Not sure if this info is of any use to you at all but I thought I would
share just in case it would.
