Created attachment 869496 [details] gnumeric file that triggers the bug This is some pretty crazy event but I can reproduce it 100% of the time simply by: 1. Opening the attached .gnumeric spreadsheet 2. Right-clicking on the 2nd chart (the bars), accessing its properties dialog 3. In the plot's hierarchy tree on the left, click the last item: "Series1" Boom. The kernel locks up: X is frozen, whatever music that was playing gets stuck into a loop, you can't switch to virtual terminals, and you have to force a hard reset by power-cycling the machine. When doing further testing, I logged myself into SSH pre-emptively and ran "journalctl -f" in the hope of glimpsing what went wrong right before the kernel goes belly up, and I was lucky enough to find out that the radeonsi driver is locking up. Attaching the output of journalctl so you can see what's going on. Would be good to have upstream know about this... Note: I also checked if gnumeric was segfaulting or anything like that by running it through gdb over SSH, but it encounters no problem whatsoever. So this is really the video driver's problem.

This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
