Bug#475112: more info: predictable way to reproduce crash

[Nicola Manini <Nicola.Manini@mi.infm.it>]

Hello,
		I found a predictable and reproducible way to obtain this X crash... 
admittedly running a non-debian piece of software.

I installed the current linux version 1.22.11.113941 of the Secondlife 
client from http://secondlife.com/support/downloads.php , logged to my 
Secondlife account, and tried to change the graphics resolution in 
Edit->Preferences.  X crashes all the times within 2 seconds.  As in my 
previous post, it is impossible to restart X afterwards.  One can just log 
into the textual console and reboot the machine.

I experienced occasional crashes of the Secondlife client in the past, but 
never induced a full crash of X.

The error log is the usual
Error in I830WaitLpRing(), timeout for 2 seconds
pgetbl_ctl: 0x00000001 getbl_err: 0x00000000
ipeir: 0x00000000 iphdr: 0x7f0000d7
LP ring tail: 0x000036f0 head: 0x00003714 len: 0x0001f001 start 0x00000000
....

I hope this helps, all the best,
						Nick
