Well that's embarassing. backtrace_symbols() calls malloc, but we call it from a signal handler, so if malloc faults, we deadlock. Now why malloc faulted, who knows. Duplicate of bug #517625? I'm currently trying to get a gdb backtrace from my machine.... I got a different backtrace. I've opened a new bug #524312 as in my case this seems to be caused by xorg-x11-drv-ati & EXA. Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages (at least F12Beta, but even better if the very latest versions). Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you. If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you. [This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.] This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping this is still happening a lot for me. Actually it started after upgrading to F12 (from F11, although clean install, not upgrade) - running F12 - all packages updated until today (Dec 23) (using main and updates repos only) 1. every so often (hard to predict when), screen completely freezes and unable to go to console. 2. ssh-ing in from another machine works and finds Xorg on 100% CPU (sometimes even over) 3. reboot seems the only option In the last few days has happened, at least a few times a day. I normally never reboot, only suspend. Not sure how to provide more information, but next time, I'll see if the "(gdb) bt" option gives anything useful. I have a Dual screen setup with my Laptop and external screen. Driver used is Radeon, nothing fancy Could you please reply to the previous question? If you won't reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you. [Note please, that this is machine generated comment for large amount of bugs; due to some technical issues, it is possible we've missed some of the responses -- it is happens, please, just a make a comment about that; that we will see. Thank you] sure, close it. I'm afraid I can't provide any more data. After having used Redhat since version 5.2, I found myself forced to switch to Ubuntu (for now), as this problem made my work impossible. I had to force-reboot (hold power down) several times a day. I tried installing backtrace stuff (like Thomas describes), but I'm unfamiliar with how that works and I never got it to work. Googling found that I'm not alone, but if you can't reproduce it, then yes, I can imagine you will need to close it "unable to reproduce". So, I am sorry, we've lost that faithful friend of RH/Fedora distros, but apparently the situation hasn't changed much from comment 1. It is obvious there is a problem, but we have no clue where. Closing as INSUFFICIENT_DATA but please reopen if you get any more information about it. Good luck with Ubuntu! |
Description of problem: Was typing in a terminal and it froze.
