[ 4847.201171] PM: late suspend of devices complete after 15.428 msecs
On my 4770 (Z87, one HDMI monitor) I get no such message, but instead the attached snd messages.
(In reply to Andreas Reis from comment #5) > [ 4847.185742] PM: suspend of devices complete after 947.984 msecs > [ 4847.190187] ------------[ cut here ]------------ > [ 4847.190203] WARNING: CPU: 3 PID: 10228 at > drivers/gpu/drm/i915/intel_display.c:9297 hsw_enable_pc8+0x5f0/0x710() > [ 4847.190204] CPU PWM1 enabled That's a different warning. Would you mind filing a new bug for it? Does this still happen on nightly with i915.fastboot=1 ? Hopefully fixed with commit 3ecc547ac1e7e1cbba13e831f7ae05c820a9e23b I get the SPLL enabled warning with Linux 4.3.0 but haven't seen it yet with drm-intel-nightly from 2015-11-30 with or without i915.fastboot=1. Probably fixed with the SPLL changes then. :) |
