Hi,

On Bugzilla, danilrybakov249@gmail.com reported stable-specific, ACPI error
regression that led into high CPU temperature [1]. He wrote:

rature and lag. After running htop noticed that journald was using 30-60% o=
f CPU. Afterwards, tried switching to stable, or lts v6.6.18-1, but encount=
ered the same issue.
