Public bug reported:
I recently upgraded a working system from Ubuntu 22.04 to 24.04. After
the upgrade, the system has acquired an eagerness to become completely
nonresponsive about a minute after logging in to a graphical session.
Logging in via console/SSH does not trigger hangs as quickly but they
still occur within a few hours typically. When logging in to a graphical
session, I notice immediately that performance and responsiveness is
heavily degraded, and within moments, the entire system locks up. Any
existing SSH sessions immediately stop responding, and the display
freezes on whatever it was previously displaying. No keyboard or mouse
input has any observable effect on the system, and it must be powered
off manually.
The system does not reboot automatically nor does it power off. I
configured linux-crashdump and triggered a kernel panic to verify that
dump files can be written successfully. However, they are not written on
this hang, implying that it is not a kernel crash.
The new Linux kernel version is 6.8.0-41, while the old kernel 6.5.0-45
is still installed. When booting into the older kernel version (no other
changes), these symptoms do not occur and function is as it was before
the 24.04 upgrade.
Seeing LP#2073358, I tested linux-oem-6.8/6.8.0-1011.11 but this has the
same behavior as 6.8.0-41-generic.
