32-bit mode GPU:Nvidia Quadro 4000M, nvidia-current 304.88-0ubuntu0.0.2 In addition to the above mentioned "NVRM: Xid ..." and "NVRM: os_schedule:..." messages, the following extra message had been appearing in dmesg, and syslog. Unfortunately, I don't see these messages in any of the other user's posted dmesgs, so my version of these symptoms, and current fix may be unrelated. --- begin dmesg snippet NVRM: Your system is not currently configured to drive a VGA console NVRM: on the primary VGA device. The NVIDIA Linux graphics driver NVRM: requires the use of a text-mode VGA console. Use of other console NVRM: drivers including, but not limited to, vesafb, may result in NVRM: corruption and stability problems, and is not supported. --- end dmesg So I decided to make sure that vesafb (and any fb stuff done by grub) were fully deactivated. I added "blacklist vesafb" to a modprobe config file, should work by placing in /etc/modprobe.d/nvidia-blacklist.conf". The problems persisted, so I added "GRUB_GFXPAYLOAD_LINUX=text" to /etc/default/grub, ran update-grub, then rebooted. Now the "NVRM: Xid ..." and "NVRM: os_schedule:..." messages have stopped, and the machine has run reliably for over a week. (The video would become corrupt, and machine would eventually hang once a day.) Of course your mileage may vary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986831 Title: system freezes for some seconds: Attempted to yield the CPU while in atomic or interrupt context To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/986831/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
