Summary: X freezes (and kernel seems to enter in deadlock)
Product: xorg
Version: 7.3
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/radeonhd
AssignedTo: lverhaegen@xxxxxxx
ReportedBy: joel.bertrand@xxxxxxxxxxx
QAContact: xorg-team@xxxxxxxxxxx


Hello,

I have found a reproductible bug. In a first time, I though that it comes from
linux kernel itself, but if I try to reproduce it without X, kernel doesn't
hang.

I use a laptop with a graphic adapter that is supported by radeonhd driver :
cauchy:[~] > lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc M76 [Radeon Mobility HD
2600 Series]

I do some complex computations and when I launch at the same time 4 or 5
process (each process take 1,6 GB, my computer has 4 GB of RAM), system swaps
and load is about 10. After few minutes, disk activity stops and X freezes.
There is no information in log files (no information on console too).

I use a debian/testing distribution with
cauchy:[~] > dpkg-query -l | grep xorg
ii xorg 1:7.3+16
X.Org X Window System

Regards,

JKB
