Public bug reported:
HP Envy x360 16-ac0xxx (Meteor Lake, Intel Core Ultra 7 155U) — xe driver HPD
interrupt storm on HDMI-A-1 at boot
On kernel 7.0.0-22-generic and 7.0.0-1005-oem, the xe DRM driver detects an HPD
interrupt storm on HDMI-A-1 within ~12 seconds of boot even with no monitor
connected, falling back to polling mode. This causes HDMI monitors to take 30+
minutes to be detected and causes repeated connect/disconnect cycling when a
monitor is plugged in.
Key dmesg line: xe 0000:00:02.0: [drm] HPD interrupt storm detected on
connector HDMI-A-1: switching from hotplug detection to polling
Parameters xe.hpd_storm_ctl and xe.enable_guc are silently ignored (unknown
parameter). Firmware is fully up to date per fwupdmgr.
