ec_intr=0 is a reasonable workaround for this box, if we couldn't root-cause and fix the real problem on time.

No, don't do this. There are other laptops need this. And I didn't get regression report that is root-caused to enabling ec_intr=1 by default. If you argue bug 5989, 6075 could be, I think the truth is, for 5989, we need to fix thermal and processor driver issue. for 6075, we need to fix interrupt issue.
So far, I don't think we need o fall back.
Thanks, Luming
