I've noticed another symptom that may or may not be related: the touchpad on
the laptop is barely responsive.  That is, dragging your finger across it
barely moves the on-screen pointer at all, and tapping or clicking very rarely
registers.  Using an external mouse works fine.

I installed kernel-default-5.19.2-lp153.4.1.ge3d4124.x86_64 from that
repository and the system runs fine, even under a sustained heavy CPU and
graphics processing load.  The buildt-in touchpad also works fine with this
kernel version.
