[Ubuntu-x-swat] [Bug 1535048] Re: i915 driver seems to cause system crash at random
*** This bug is a duplicate of bug 1554613 *** https://bugs.launchpad.net/bugs/1554613 Tried it and lo and behold, I got a crash eventually, although it took way longer in the regular usage scenario. I am not sure if the TLP settings are implemented correctly though. On one occasion i7z told me turbo mode was enabled although I disabled it n TLP settings.. That was when I saw the crash happen. I then manually disabled turbo mode " echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo" after which it showed that it was indeed disabled. No clue as to why this was the case. Another thing I notice is that when I configure it to use : CPU_MIN_PERF_ON_AC=100 CPU_MAX_PERF_ON_AC=100 CPU_MIN_PERF_ON_BAT=0 CPU_MAX_PERF_ON_BAT=100 I expect it to change operatig mode when I plug or unplug the power cable. I does not however, as i7z reveals. Seems like it sustains the mode that was to be chosen based on the situation at boot time. It is not modified during runtime. All in all I am hoping to discover that effective deactivation of turbo mode might be the fix for me. I don't believe my situation is a duplicate of bug #1554613. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1535048 Title: i915 driver seems to cause system crash at random To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1535048/+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

*** This bug is a duplicate of bug 1554613 *** https://bugs.launchpad.net/bugs/1554613 Very similar situation here, however: In my case there is absolutely no prediction of crashing. It just happens: instant shutdown followed by automatic reboot. Nothing to be seen in the logs. Happens under moderate load ; have yet to see it happen under full load (benchmark) or idle mode. So my problem might be related. The problem exists in many different Linux distros. On one particular kernel on Opensuse leap 42.2 the problem did not occur, until I updated the kernel. Never happened in windows 10 that I used moderately for editing a 3d model. Interval is random: can happen within 10 minutes when playing 0ad or upto days when performing simple office/multimedia tasks. Quite annoying but very similar, yet slightly different to your problem I guess. Similar hardware: i5 6267 with iris 550 graphics. I will try your solution as soon as I have access to the laptop again. It will implicate reduced battery life I fear though if I see this correctly?!? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1535048 Title: i915 driver seems to cause system crash at random To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1535048/+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

*** This bug is a duplicate of bug 1554613 *** https://bugs.launchpad.net/bugs/1554613 New test result today seems to be a intel P-state related problem. I had reverted everything to their default state, with only the following changes in TLP settings: /etc/default/tlp # Set Intel P-state performance: 0..100 (%) # Limit the max/min P-state to control the power dissipation of the CPU. # Values are stated as a percentage of the available performance. # Requires an Intel Core i processor with intel_pstate driver. CPU_MIN_PERF_ON_AC=100 CPU_MAX_PERF_ON_AC=100 CPU_MIN_PERF_ON_BAT=100 CPU_MAX_PERF_ON_BAT=100 Now the machine never crashed no matter what tricked I played against it. This workaround seemed to work both under a normal Linux kernel and a realtime kernel. I guess the crash was triggered by flipping the P-state to save power. In the previous report I was using WebGL Aquarium to do the test, which has a rather linear stress. But later when I was using Krita, whose stresses on the CPU comes in spikes, the old workaround failed to work. When connecting to an external monitor, it also did not crash anyway but I guess it was using full power all the way because of the dualview requires that much power. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1535048 Title: i915 driver seems to cause system crash at random To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1535048/+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

*** This bug is a duplicate of bug 1554613 *** https://bugs.launchpad.net/bugs/1554613 I did a few more tests. On my system, the combination of a realtime (lowlatency) kernel and certain tlp settings fixed the random crash. Although the side effect was the machine can get very hot because CPU threads cannot be turned off. Processor: Intel® Core™ i7-6567U Graphics: Intel® Iris Graphics 550 (Skylake GT3e) Linux kernel: 4.11.12-1-rt16-MANJARO TLP modified settings (/etc/default/tlp): SCHED_POWERSAVE_ON_AC=0 ENERGY_PERF_POLICY_ON_AC=normal Note: this combination also solved the intel 8265 bluetooth random disconnection and reconnection failure on this machine. All these tests were carried out on Manjaro, but I did suffered similar problem when I was testing Ubuntu 17.10.

*** This bug is a duplicate of bug 1554613 *** https://bugs.launchpad.net/bugs/1554613 Hi, First of all this IS NOT A DUPLICATE OF BUG #1554613. This is an entirely different problem which is quite consistent in its behaviour when it fails. As the original creator of this bug reported, the problem happens whenever it feels like, it can happen in 10 minutes or 2 hours, or not at all (if you lucky). Mostly its been happening all the time to me. Sometimes I get a lucky roll of the dice and it works for a bit. The problem is to do with the i915 kernel module. When the random problem occurs, the system freezes dead in its tracks in the moment it freezes and you have to power off and on again. Very annoying problem. Not wanting, but feeling forced to goto Windows temporarily. Please can this bug be treated high priority. I can not enjoy any games on Linux whatsoever due to this bug. This happens playing any game for me. It can happen after 15 minutes of playing a game, or 1 hour. Please can you guys first fix that this is not a duplicate of #1554613 and could you guys help to assist to get whatever is wrong with i915 module fixed?

[Ubuntu-x-swat] [Bug 1535048] Re: i915 driver seems to cause system crash at random
It's very similar and i do sometimes experience the flickering as a precursor to the complete crash, but mostly screen goes off and it just crashes. Actually it freezes the whole PC. Keyboard is unresponsive. I installed kdump, set soft, nmi etc. watches on but the PC does not detect the crash and does not boot the second kernel :( and i dont have a nmi button. All i can is power off and restart. Got ideas, how i can trigger the kernel dump? Also i did experience the same issue with 15.10.
