Hi again.
What makes you think that the problem is related to the uvcvideo driver?
Does some previous kernel version work correctly? If so, what version(s)?
Does this warning message only happen when the uvcvideo driver is being loaded?
Can you suppress loading of the uvcvideo driver to find out?
Most of the problems/errors/warnings that I see are related to the i915 driver:
[ 13.032341] timed out waiting for port C ready: got 0x20, expected 0xe0
[ 13.032872] WARNING: CPU: 1 PID: 239 at drivers/gpu/drm/i915/intel_display.c:1597 vlv_wait_port_ready+0x99/0xe0 [i915]
[ 13.033632] RIP: 0010:vlv_wait_port_ready+0x99/0xe0 [i915]
although there are a few uvcvideo warnings:
[ 13.039305] uvcvideo 1-5:1.0: Entity type for entity Extension 4 was not initialized!
[ 13.039318] uvcvideo 1-5:1.0: Entity type for entity Extension 3 was not initialized!
[ 13.039330] uvcvideo 1-5:1.0: Entity type for entity Processing 2 was not initialized!
[ 13.039339] uvcvideo 1-5:1.0: Entity type for entity Camera 1 was not initialized!
Laurent, do you see any uvc issues here? Any ideas/suggestions?
@intel-gfx: any ideas about what is going on here with the i915 driver?
