Bug Description
On my very old laptop, that is equipped with an Ati Mobility Radeon X700, sometimes (and, sadly, I have to use this word, because I found no regularity pattern for the occurrence of this bug) randomly the desktop session locks, that is I can only move the mouse pointer, but I cannot interact anymore with the desktop session. I am forced to login trough ssh from another pc and to restart the laptop.
In Xorg.0.log I found these lines that are, in my opinion, related to the crash:
(EE) [mi] EQ overflowing. Additional events will be discarded until existing events are processed.
(EE)
(EE) Backtrace:

Today the same crash occurred, and this time I found nothing relevant in /var/log/ Xorg.0. log, but there is something in syslog:
