In both: https://bugzilla.redhat.com/show_bug.cgi?id=989718 https://bugzilla.redhat.com/show_bug.cgi?id=996973 reporters mentioned that sometime in 3.11.X the issue had gone. So this one is just not fixed yet. Issue goes back in similar forms to 3.1.X: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=656196
This issue still occurs regularly on my machine.

Looks like the screen has been sliced in to a series of irregular triangles like a puzzle and not assembled correctly. I am the only user, so pressing enter, then typing in my password brings up the desktop. If I log out later, the login screen is displayed properly. I have used Fedora on this laptop since it was new and 19 is the only version I've used that has behaved this way.

Created attachment 857157 [details] amd_e400_c1e_clockevents.patch Proposed fix for the bug. I launched kernel build with it here: http://koji.fedoraproject.org/koji/taskinfo?taskID=6468631 (bz1058268 number in the name is wrong, but that kernel includes proper patch) Please test it, it can make problem gone, but either can crash the kernel :-)
Any test results /re kernel from comment 15 ?
(In reply to Stanislaw Gruszka from comment #16) > Any test results /re kernel from comment 15 ? Forgive my ignorance, can you provide the steps for me to update my kernel with your build? Then, I will run your kernel for a week or so and see if this bug occurs. Will that suffice?
You have to download kernel package from above link for your architecture, i.e. for x86_64 it would be: > http://kojipkgs.fedoraproject.org//work/tasks/8635/6468635/kernel-3.12.9-301.bz1058268.fc20.x86_64.rpm Then install it using rpm -ivh kernel-3.12.9-301.bz1058268.fc20.x86_64.rpm command. If there will be dependency or other installation problem, you can use --force and --nodeps rpm options. Then boot into new installed kernel.
Sorry for the delay. I just installed your kernel. $ uname -rvs Linux 3.12.9-301.bz1058268.fc20.x86_64 #1 SMP Wed Jan 29 17:26:47 UTC 2014 I'll report back in a week or so (or earlier if this bug shows up).
I just got this bug using the following kernel: $ uname -rvs Linux 3.12.9-301.bz1058268.fc20.x86_64 #1 SMP Wed Jan 29 17:26:47 UTC 2014
Created attachment 861273 [details] tick_broadcast_v2.patch New patch, hopefully this one would be better. Kernel build with the launched here: http://koji.fedoraproject.org/koji/taskinfo?taskID=6511401 Please test it.

http://marc.info/?l=linux-pm&m=139212870024923&q=raw http://marc.info/?l=linux-kernel&m=139212871024925&q=raw Subject: tick: Clear broadcast pending bit when switching to oneshot From: Thomas Gleixner <tglx> Date: Tue, 11 Feb 2014 14:35:40 +0100 AMD systems which use the C1E workaround in the amd_e400_idle routine trigger the WARN_ON_ONCE in the broadcast code when onlining a CPU. The reason is that the idle routine of those AMD systems switches the cpu into forced broadcast mode early on before the newly brought up CPU can switch over to high resolution / NOHZ mode. The timer related CPU1 bringup looks like this: clockevent_register_device(local_apic); tick_setup(local_apic); ... idle() tick_broadcast_on_off(FORCE); tick_broadcast_oneshot_control(ENTER) cpumask_set(cpu, broadcast_oneshot_mask); halt(); Now the broadcast interrupt on CPU0 sets CPU1 in the broadcast_pending_mask and wakes CPU1. So CPU1 continues: local_apic_timer_interrupt() tick_handle_periodic(); softirq() tick_init_highres(); cpumask_clr(cpu, broadcast_oneshot_mask); tick_broadcast_oneshot_control(ENTER) WARN_ON(cpumask_test(cpu, broadcast_pending_mask); So while we remove CPU1 from the broadcast_oneshot_mask when we switch over to highres mode, we do not clear the pending bit, which then triggers the warning when we go back to idle. The reason why this is only visible on C1E affected AMD systems is that the other machines enter the deep sleep states via acpi_idle/intel_idle and exit the broadcast mode before executing the remote triggered local_apic_timer_interrupt. So the pending bit is already cleared when the switch over to highres mode is clearing the oneshot mask. The solution is simple: Clear the pending bit together with the mask bit when we switch over to highres mode.
