Comment 16 for bug 359392

I hope that those who find they need to reboot because of the freeze have at least tried RSEIUB , if used correctly
it can prevent filesystem damage here is a link to how its used.. http://techpatterns.com/forums/about911.html
I have noticed that `intel_reg_dumper`, which is available as part of the xserver-xorg-video-intel-dbg package
reveals the register that is being changed when the freeze occurs, running it before and after the crash and using
sudo intel_reg_dumper > reg_good.txt before the crash and sudo intel_reg_dumper > reg_bad.txt after the crash
from a ssh session to the sick machine and then doing sudo diff reg_good.txt reg_reg_bad.txt will show the register
that is changing .
 diff reg_good.txt reg_bad.txt
140c140
< (II): MI_MODE: 0x00000200
---
> (II): MI_MODE: 0x00000000
and then
wirechief@wirechief-laptop:~$ cat reg_bad.txt |grep MI_MODE
(II): MI_MODE: 0x00000000
wirechief@wirechief-laptop:~$ cat reg_good.txt |grep MI_MODE
(II): MI_MODE: 0x00000200
I am reading in other bug reports this is the common indication that the freeze issue has occurred.
