Control: severity -1 grave

Raising severity, since this current kernels are completely unusable on
at least some hardware (i.e. the one I use here), since the temperature
just explodes.
I'd say grave is justified already by potential hardware damages of
systems running even at little actual load at 100 °C not to talk about
the fact that one can effectively not upgrade to >5.2 kernels and thus
miss any security updates.


I've just checked the 5.4 packages from sid and the described issue
still occurs.


It seems to me that it's likely somehow graphics related, cause if I do
nothing (i.e. the screen also does nothing) the temperatures go down to
acceptable ~60°C .. but if I just scroll up and down e.g. in my email
client's mail list (which ist just the list of subject/from/etc.
lines), the temperature goes up to 80°C

And still, as previously described, even if I stop the actions that
caused the temperatures going up (like no longer scrolling up/down) it
takes quite a while till CPU temperatures go down again (eventually
they do).


Downgrading to 5.2 and everything's back to normal.


Cheers,
Chris.
