[Intel-gfx] periodic wakeup from DPMS suspend

Hi, I have a NEC EA244WMi monitor connected to an Asus P8H77-V mainboard with Ivy Bridge Core i5-3550 via DVI. If DPMS suspend is enabled (by xscreensaver, or for testing by "xset dpms force off/suspend/standby"), the monitor enters standby mode but wakes up every 10...30 seconds for 6 seconds to

Hi, I updated the Linux kernel on an old machine from v6.5.9 to current v6.8.8 and found the display failed after resume from suspend to RAM. Then I tried v6.7.9 and v6.6.29, both also failed. v6.5.9 works. - display connected via display port: hangup - I also tried HDMI with v6.6.29: garbage (c

Re: i915 IVB hangup after resume from s2mem since v6.6.x

Hi Jani, thank you for the quick response. Currently the machine is in use and I cannot crash and reboot it at will. I will file the bug report in the next days when I gathered the requested logs. I might as well git bisect it, otherwise I guess the root cause would be hard to find. Thanks, Joha
