Requested logs with drm.debug=6 are attached. lightdm was running after WARN_ON, but I couldn't restart it. The command hanged. As I booted next-20150202 system crashed several times with a lot of drm_ calls in the backtrace, but I couldn't catch kernel logs, because I have not serial port on the laptop. If you need to get other information or to test patches, I would be glad to help. -- Best regards, Andrey Skvortsov PGP Key ID: 0x57A3AEAD -- next part -- [0.00] Initializing cgroup subsys cpuset [0.00] Initializing cgroup subsys cpuacct [0.00] Linux version 3.19.0-rc6-next-20150202-150201- (developer at ST-37) (gcc version 4.7.2 (Debian 4.7.2-5) ) #4 SMP PREEMPT Mon Feb 2 17:53:17 MSK 2015 [0.00] Command line: BOOT_IMAGE=/boot/vmlinuz-3.19.0-rc6-next-20150202-150201- root=UUID=b8e95798-f113-470b-b415-323e51da7052 ro drm.debug=6 [0.00] e820: BIOS-provided physical RAM map: [0.00] BIOS-e820: [mem 0x-0x0009efff] usable [0.00] BIOS-e820: [mem 0x0009f000-0x0009] reserved [0.00] BIOS-e820: [mem 0x0010-0xdf66d7ff] usable [0.00] BIOS-e820: [mem 0xdf66d800-0xdfff] reserved [0.00] BIOS-e820: [mem 0xf800-0xfbff] reserved [0.00] BIOS-e820: [mem 0xfec0-0xfec0] reserved [0.00] BIOS-e820: [mem 0xfed18000-0xfed1bfff] reserved [0.00] BIOS-e820: [mem 0xfed2-0xfed8] reserved [0.00] BIOS-e820: [mem 0xfeda-0xfeda5fff] reserved [0.00] BIOS-e820: [mem 0xfee0-0xfee0] reserved [0.00] BIOS-e820: [mem 0xfff0-0x] reserved [0.00] BIOS-e820: [mem 0x0001-0x00019fff] usable [0.00] NX (Execute Disable) protection: active [0.00] SMBIOS 2.4 present.

Right, here it looks like it freezing in intel_get_load_detect_pipe() during the initial configuration probe of X.

Those two warnings are more or less symptoms of the black screen (well the first is just overzealous). More important would be the drm.debug=6 dmesg from boot along with the gdm.log (or equivalent) aned Xorg.0.log as my guess is that X (or the display server) is crashing. -Chris -- Chris Wilson, Intel Open Source Technology Centre
