I know this will be difficult but when you are under sunlight it's possible you will see something. So when you think the system is up and waiting for your input enter your username and then password. In bottom left corner there should be Terminal shortcut - click it! Now type su, and after that type in your ROOT password! When done try this:
Code:
setpci -s 00:02.0 F4.B=00
If this helped navigate in /etc/rc.d/rc.local:
Code:
nano /etc/rc.d/rc.local
Now add this line:
Code:
/sbin/setpci -s 00:02.0 F4.B=00
After you are finished rc.local should look something like this:
Code:
#!/bin/sh
#
# /etc/rc.d/rc.local: Local system initialization script.
#
# Put any local startup commands in here. Also, if you have
# anything that needs to be run at shutdown time you can
# make an /etc/rc.d/rc.local_shutdown script and put those
# commands in there.
/sbin/setpci -s 00:02.0 F4.B=00
Now this will start automatically with your system. Remember this is just a temporary solution, and as soon as new kernel is released upgrade to it. Hopefully this bug will be fixed by then! Good luck!
