Hotplug irqs from eDP, I vaguely recall Ville fighting with something like this on BSW. Update the BIOS to >= V61. Yes. Ville first found out this issue. Ville, I vaguely remember that V61.3 also has this issue. Since my test machine has an issue that eDP is black with DP monitor connected for V61.3 and V68.1 BIOS, I downgraded BIOS to V59 for testing. Exists on drm-intel-testing-2015-05-08 (In reply to Jeff Zheng from comment #4) > Exists on drm-intel-testing-2015-05-08 No one cares if you use a known broken BIOS. Please reopen if the problem is present with a newer BIOS. Created attachment 115787 [details]
dmesg on BIOS V69
Upgraded to V69, and there are still many hotplug events
Don't see this issue on drm-intel-testing-2015-05-22 + V69. Close. Closing old verified. |
