Hi.
I am having a (not so) funny kind of issue. The issue seems that my CPU
seems to enter into a bad 'state', where even in idle it is in C0 for
2/3rds of the time. In this state, the interrupts per second go to more
than 20K per second!! This is in contrast to the usual nice state, where
I have about 153 per second and its in C3 for more than 95% of the time.
(When I start the notebook, its in the 'good state', and it goes into
this bad state arbitrarily and never returns. (The transition happens
I've seen this once myself, and a few others have reported sporadic
sightings as well.... but so far it's only happening when we can't see
what's going on.. it's one hard case to chase down.
it seems you can reproduce this a lot more than I or anyone else could
so far, so maybe you can help chase this one down.
As a start, can you take a
lspci -vvxxx > lspci.good
in the "good" state as well as a
lspci -vvxxx > lspci.bad
in the "bad" state, so that we can compare the two?
