#StackBounty: #gnome #keyboard #xorg #gdm why am i getting ' event processing lagging behind' msg in Ubuntu 20.10

Bounty: 50

seeing my system logs, they are full of msgs like this:

/usr/libexec/gdm-x-session[2564]: (EE) event4  - SIGMACHIP USB Keyboard: client bug: event processing lagging behind by 25ms, your system is too slow
/usr/libexec/gdm-x-session[2564]: (EE) event4  - SIGMACHIP USB Keyboard: client bug: event processing lagging behind by 17ms, your system is too slow

i have a 12 core system which is essentially idle when i see this. it seems to happen since i upgraded to Ubuntu 20.10.

how can i find the root cause and how to eliminate this issue?

sys info:
