[Ubuntu-x-swat] [Bug 1763273] Re: kernel panic in Radeon driver while screen blank
After several weekends of testing, I believe I can report with high confidence that the kernel update to 4.17-rc2 fixes the second of the two problems; specifically, we no longer see kernel crashes after using Alt-SysRq-k to recover from frozen/hanging blank screens. However, the unable-to-unblank problem remains; after normal screen blanking, about 50% of the time we are unable to recover by moving the cursor or typing a key. Instead, only Alt-SysRq-k allows us to recover back to a guest login screen. There doesn't seem to be much in the system logs that I can find, except possibly this: May 20 20:41:04 Comprm8 gnome-session[7919]: gnome-session-binary[7919]: GLib-GIO-CRITICAL: g_dbus_connection_call_internal: assertion 'object_path != NULL && g_variant_is_object_path (object_path)' failed May 20 20:41:04 Comprm8 gnome-session-binary[7919]: GLib-GIO-CRITICAL: g_dbus_connection_call_internal: assertion 'object_path != NULL && g_variant_is_object_path (object_path)' failed Some seemingly similar bug reports from out in the wild: https://askubuntu.com/questions/795014/ubuntu-16-04-occasionally-hangs-with-screen-off-after-switching-ttys-or-turning https://askubuntu.com/questions/949764/ubuntu-hangs-when-unlocking-screen Can you recommend any approaches to help debug the root cause of this problem, presumably in X and/or the radeon driver? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1763273 Title: kernel panic in Radeon driver while screen blank To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763273/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1763273] Re: kernel panic in Radeon driver while screen blank
Hit another kernel panic this weekend, again after having the screen go blank and be unblankable via any normal method, then trying Alt-SysRq-k and getting this panic (with a different stacktrace than the other, but also going through the radeon driver and radeon_crtc_handle_flip). I'll try to get the kern.log file matching this panic next weekend. ** Attachment added: "radeon_kernel_panic2.jpg" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1763273/+attachment/5126315/+files/radeon_kernel_panic2.jpg -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1763273 Title: kernel panic in Radeon driver while screen blank To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763273/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

One further historical detail: when these machines were running 14.04.3 and we made the mistake of accepting the HardWare Enablement (HWE) upgrade: https://wiki.ubuntu.com/1404_HWE_EOL which replaced the old fglrx driver with the radeon one, that's when we first encountered this unable-to-unblank problem. Fortunately, at that time we were able to roll back Xorg to 1.16 and keep things sort-of working: https://askubuntu.com/questions/815591/ubuntu-14-04-5-16-04-and-newer-on-amd-graphics https://askubuntu.com/questions/676216/downgrade-xorg-server When we performed a clean, full re-install with 16.04 we were hoping this problem would be resolved, but as I've documented here it continues to affect the systems. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1763273 Title: kernel panic in Radeon driver while screen blank To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763273/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1763273] Re: kernel panic in Radeon driver while screen blank
While logged in via ssh to the machine with the "hung" Xorg (screen blank, no way to recover except Alt-SysRq-k), I dumped the output of Alt-SysRq-t into the syslog -- see attached file. Not sure this is much use, however. Just trying to be complete while I'm on-site with a hung machine. ** Attachment added: "syslog with output from Alt-SysRq-t in ssh session" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1763273/+attachment/5117347/+files/syslog -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1763273 Title: kernel panic in Radeon driver while screen blank To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763273/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1763273] Re: kernel panic in Radeon driver while screen blank
Further debugging today while I'm on-site with the kiosks. The system froze, as usual, after normal idle screen blanking. I was able to login via ssh and retrieve some details. First, it appears that the basic screen blanking problem is somehow related to the Radeon driver. I will attach the Xorg.0.log file and a gdb backtrace on the running but non-responsive Xorg process. No keyboard or mouse activity will un-blank the screen. Here's the output from lspci | grep VGA: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV516 [Radeon X1300/X1550 Series] I'll also attach the PCI ROM dump from the /sys/devices rom file for this device. This suggests that when we use Alt-SysRq-k to restore the system, sometimes we trigger *another* bug in the driver which results in the overall system crash. See the attached apr1.full.kern.log file for what details I could recover from the crash on April 1st; that corresponds to the screen photo I took that day (the radeon_kernel_panic1.jpg attachment). The Xorg "hang" bug which precedes this appears similar, but not identical, to what is documented in #1664979: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1664979 I will continue to try to study the live Xorg process to see if I can determine where its hung, but I may not have time this evening. Let me know if there are specific further debugging steps I can take to examine either the Xorg hang or the subsequent crash which (sometimes) follows on attempting to recover with Alt-SysRq-k. (And note that I'll copy in the files apport-bug generated from #1764211 later tonight, using my "cdarroch" personal account, and then I'll try to close that extra bug report.)

I'm only on-site with these kiosks once a week, but the next time I'm there I will run apport-collect on one of the affected systems, and see if we can't capture the problem. I'll also investigate whether there are any messages in kernel log files, as best I can. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1763273 Title: kernel panic in Radeon driver while screen blank To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763273/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
