So hard to know what's the pattern but you can see the following from status register prints: * in the patched kernel burst mode is turned off before suspend-to-idle ent= ry * in the unpatched kernel the input buffer is full * in the patched kernel a "polling quirk" occurs meaning enabling EC didn't trigger a GPE I guess more test runs will confirm whether this is consistently the same behavior. --=20 You may reply to this email to add a comment.
