[Nouveau] [Bug 102631] New: Multiple nouveau stacks on kernel log when connecting a external monitor
https://bugs.freedesktop.org/show_bug.cgi?id=102631 Bug ID: 102631 Summary: Multiple nouveau stacks on kernel log when connecting a external monitor Product: Mesa Version: 17.1 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/nouveau Assignee: nouveau at lists.freedesktop.org Reporter: emilio at crisal.io QA Contact: nouveau at lists.freedesktop.org Created attachment 134100 --> https://bugs.freedesktop.org/attachment.cgi?id=134100&action=edit relevant dmesg output Sorry for the non-descriptive bug title in advance, I'm not sure which parts of the logs are worth a bug report, but I'm moderately sure that something in here deserves a bug filed. My machine is a Lenovo P50 with: VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M2000M] (rev a2) And mesa version 17.1.8 I connected an external monitor to the HDMI port, and I got black screens for a few retries. On an unrelated (maybe not so unrelated?) note, I get reproducible FAULTs on startup, regardless of any monitor attached or not I believe. I also got some others on today's log, but that may be just related to the problem above. The first two lines below repro even without an external monitor: [ 2.690083] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 022554 [ IBUS ] [ 2.691514] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 10ac08 [ IBUS ] [ 23.396822] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 690000 [ TIMEOUT ] [ 41.791019] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 690000 [ TIMEOUT ] [ 41.791902] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 6900c0 [ TIMEOUT ] [ 51.876682] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 690000 [ TIMEOUT ] [ 61.915247] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 690000 [ TIMEOUT ] [ 75.297725] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 690000 [ TIMEOUT ] Happy to help providing more information, testing, or even trying to contribute a fix (with some guidance ideally, since I know nothing about the driver's code :P). Thanks a lot in advance. -- You are receiving this mail because: You are the assignee for the bug.
