Temporal, thank you for reporting this and helping make Ubuntu better. Could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please just make a comment to this.
If reproducible, could you also please test the latest upstream kernel available from the very top line at the top of the page (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.16-rc1 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Description changed: - As nothing changed, I'll just copy-paste(and update) what I said in - bugs.launchpad.net/ubuntu/+source/linux/+bug/986831 : - I can reproduce consistently and a almost at will the "NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt - context" problem: - - Ubuntu: x64, 13.10, kernel 3.11.0-23-generic; - HD SSD OCZ octane 128GB. - Intel Q9400; - Motherboard: P5n-D; - Memory: 2x Macrovision 5-5-5-18; 2x2GB - 2x Kingston 6-5-5-18; 2x2GB - --->running in successfull Dual Channel 8GB 6-5-5-18; - GPU 1: 9600 GT 512MB; - GPU 2: 9600 GT 512MB; - --->running in successful SLI; - --->running using nvidia drivers 319 proprietary. - PSU: Corsair CX600 V2 (does not look like a problem). - - How I reproduce the problem: + context". 1)Run World of Warcraft (via Wine-any Wine that works WoW x32 will do, I tried with 1.4 and 1.5-), go to the latest levels (pandaria). 2)Open any browser and go to youtube, let it running videos from any playlist. 3)Soon after, the X server will start to stutter, and DMESG will show the "NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context" problem. 4)Usually, if I get to catch the problem, the kernel process that switches processes around (mostly the first of 4) called migration (in my case, migration/0) will appear running at 100%. If I run just the game or just the browser, everything runs perfectly. SLI works randomly for WoW if running in full screen. SLI is always working while in Unity. If I try to run GPU testers like furmark (for linux) under the same conditions I cannot reproduce the problem. BUT: After running the "ubuntu-bug linux" and in dmesg appeared this: "Watchdog[18072]: segfault at 0 ip 00007f308b0c1738 sp 00007f307c6026f0 error 6 in libcontent.so[7f308a979000+fb2000]" everything is working fine now?! I don't know what happened, all that I always do when the problem happens, I go to tty1 and run top, go to tty2 and run tail -f /var/log/syslog, and keep switching between 1, 2 and 7. - - I hope this helps someone.
