Reverting the patch helps now, but > is not very future-proof. The problem is not with HW but with SW - "optimize resuming from S4" broke bandwidth calculations which the driver performs for old HW that cannot do them itself. That's why new HW works without issues. The driver obviously needs to be fixed, maybe Lovekesh will find the remaining issues (already found one), or if not, I am alerting the original culprits right now. IMHO reverting this in mainline would be fine too - the "optimization" is negligible while it costs bugs and copy-pasted code. Regards, Michal --=20 You may reply to this email to add a comment.
