Hi, I'm hitting this reliably on every resume on 3.15.5. (libdrm 2.4.54, mesa 10.2.3) relevant dmesg output : juil. 11 17:28:23 Nemmerle kernel: [drm:i965_irq_handler] *ERROR* pipe B underrun juil. 11 17:29:52 Nemmerle kernel: [drm:init_ring_common] *ERROR* render ring initialization failed ctl 0001f001 head 00000268 tail 00000000 start 007510 juil. 11 17:29:52 Nemmerle kernel: dpm_run_callback(): pci_pm_resume+0x0/0xb0 returns -5 juil. 11 17:29:52 Nemmerle kernel: PM: Device 0000:00:02.0 failed to resume async: error -5
Kwin crashes really bad after this happens... Not sure if the pipe B underrun is related, as that happens even without resuming. This is on : 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) If I can help in any way, let me know... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1339939 Title: [Lenovo ThinkPad T400] intel graphics fail after suspend with 3.15 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1339939/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
