I assume you have tested ec_intr=0 and ec_intr=1.

I need calltrace for this

Clealy, it's thermal related. We need to narrow down here.

The ground rule is Don't use modified DSDT.
If you do that,  the results won't be trusted.

Interesting, open bug for this.

ok, we need to start from thermal.  

BTW, do you still think this is a regression?
