--- Comment #3 from Martin Steigerwald <mar...@lichtvoll.de> 2010-07-13 10:24:05 --- I did some research on the internet and found this possibly related case - hot, since it also happens on a ThinkPad T42 with similar if not same graphics hardware: ------------------------------------------------------ Random freezes with kernel 2.6.34 and xorg 1.8 The other day I upgraded the kernel to version 2.6.34 and at the same time xorg-server to 1.8 (along with input drivers and video drivers). From that moment, I suffer from random freezes, the system is completely locked up; the screen doesn't blank, though. The system appears to be perfectly fine, but after some minutes it will freeze. As far as I can remember, the freezes only occur when using a webbrowser. Chromium is my default browser, but also Firefox and Konqueror caused the system to freeze completely when I want to open a webpage. Other network programs such as irssi can run for hours and they didn't seem to cause any havoc. At first I thought this might be caused by some instability in the latest xf86-video-ati driver, so I downgraded back to xorg-server 1.7. Still the same symptoms, so I am pretty sure now there's something in the kernel. So I went back to xorg-server 1.8 and downgraded the kernel to 2.6.33. So far, the system hasn't let me down, yet. Also, I uninstalled the madwifi packages on my system so I'm using the ath5 drivers shipped with the kernel. That change doesn't seem to make a difference. I am not exactly sure what exactly could cause this, there's no trace in any log file to be found. My suspicion is that it's network related. The hardware is a Thinkpad T42 with an ATI Radeon Mobility 9600 (r300) chip and an Atheros wireless card. Anyone else with similar experiences with this hardware? I can't think of a way how to properly debug this. I know I can bisect, but that's time consuming and perhaps it's quicker to ask around first before I walk down that road. Any suggestions are welcome on how to track this down ------------------------------------------------------ http://bbs.archlinux.org/viewtopic.php?pid=789948 I do not use any wireless however, the ipw2200 radio is disabled here. Unlikely cause it seems to be easily reproducable: ------------------------------------------------------ seems to freeze on drm installation [2.6.34, 2× RV280] See attached screenshot. While I can boot anything up to 2.6.33, 2.6.34 seems to reproducibly hang itself up when it starts DRM. This machine has two Radeon RV280 cards. ------------------------------------------------------ http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=586137 -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
