UPD: Solved (facepalm...) Found a process in my own script that checked whether external display is connected every few seconds. I wish I could delete the thread, but looks like I don't have this option, so it will have to hang here in the Hall of Shame.
Here's a headscratcher... Started having this issue today - my X is now locking up for a second every ~ 4 seconds. Mouse pointer still remains alive, just no GUI response. Every 4 seconds having these lines appearing in X.0.org, coinciding with lock-ups:
Happens only when drm-kmod is used. Does not happen with scfb. Started just now by itself on Thinkpad P14s. drm-kmod is built from source. CPU temperatures normal (about 70 deg.) Rebooting/power-offs do not help. It happened before, but I could always cure it by powering off. Now powering off is not helping. Happens only when external display is connected. Tried wiggling HDMI cable - does not help. No anomalies in systat -vmstat io. No other errors in logs.
Also, this only happens only under a user account. When X is started by root, no lock-ups, so it's not a hardware issue. No periodic user jobs in cron, no processes I can see that could interfere.
Any ideas?
