Ugh, I don't know why it submitted the bug in the middle of editing. Anyway, I get crashes consistently with kernels in the 3.14 series. The last kernel that worked for me was 3.13.10-200.fc20. I have a kernel dump and a backtrace: crash> bt PID: 0 TASK: ffff880129b2df00 CPU: 1 COMMAND: "swapper/1" #0 [ffff88012fc43ad0] machine_kexec at ffffffff8104f211 #1 [ffff88012fc43b28] crash_kexec at ffffffff8110a9d2 #2 [ffff88012fc43bf8] oops_end at ffffffff816f8658 #3 [ffff88012fc43c20] no_context at ffffffff816eb81d #4 [ffff88012fc43c70] __bad_area_nosemaphore at ffffffff816eb8b3 #5 [ffff88012fc43cb8] bad_area_nosemaphore at ffffffff816eba1d #6 [ffff88012fc43cc8] __do_page_fault at ffffffff816faf70 #7 [ffff88012fc43dd0] do_page_fault at ffffffff816fb442 #8 [ffff88012fc43df0] page_fault at ffffffff816f7a88 [exception RIP: radeon_driver_irq_handler_kms+27] RIP: ffffffffa00f5a3b RSP: ffff88012fc43ea8 RFLAGS: 00010086 RAX: 0000000000000000 RBX: ffff880036993800 RCX: 00000000fffffffa RDX: 0000000000000000 RSI: ffff880036993800 RDI: ffff88003656c000 RBP: ffff88012fc43eb0 R8: ffff880036932a00 R9: ffff88012ac00000 R10: 000000000000002d R11: 0000000000000001 R12: 000000000000002b R13: 00000000000000c1 R14: 0000000000000000 R15: 0000000000000000 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 #9 [ffff88012fc43eb8] handle_irq_event_percpu at ffffffff810e57fe #10 [ffff88012fc43f00] handle_irq_event at ffffffff810e59c7 #11 [ffff88012fc43f28] handle_edge_irq at ffffffff810e858f #12 [ffff88012fc43f40] handle_irq at ffffffff810169ff #13 [ffff88012fc43f78] do_IRQ at ffffffff8170284f --- <IRQ stack> --- #14 [ffff880129b7fdb8] ret_from_intr at ffffffff816f776d [exception RIP: native_safe_halt+6] RIP: ffffffff81054566 RSP: ffff880129b7fe68 RFLAGS: 00000246 RAX: 0000000000000000 RBX: ffff880129b7fdf0 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffff880129b7fe9c RDI: 00000000c0010055 RBP: ffff880129b7fe68 R8: 0000000000000000 R9: ffff880129ba2a00 R10: 0000000000000400 R11: 0000000000000001 R12: ffff880129b7fde0 R13: ffff880129b7fdf0 R14: ffff880129b7fdd0 R15: ffff88012fc4dcc0 ORIG_RAX: ffffffffffffff3e CS: 0010 SS: 0018 #15 [ffff880129b7fe70] default_idle at ffffffff8101df6f #16 [ffff880129b7fe90] amd_e400_idle at ffffffff8101e05e #17 [ffff880129b7feb8] arch_cpu_idle at ffffffff8101e866 #18 [ffff880129b7fec8] cpu_startup_entry at ffffffff810e4d05 #19 [ffff880129b7ff28] start_secondary at ffffffff81044f9b which I only managed to reproduce with kernel-3.14.6-200.fc20 by booting first into text mode and then starting X from the console.

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.
