Bug ID: 93610
Summary: X session crashes with EQ overflowing
Product: xorg
Version: 7.5 (2009.10)
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
Assignee: xorg-driver-ati at lists.x.org
Reporter: qzerty at gmail.com
QA Contact: xorg-team at lists.x.org
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.
