Ping Ville Syrjala, any update? Do the patches on bug 81948 fix this? They did for me. (In reply to comment #4) > Do the patches on bug 81948 fix this? They did for me. Yes, this patch works. Latest -nightly kernel(49ceddc7b3b0e3f7eb21b9fb4c9b840cff630047) works well when machine resume from s3. I think we can close this bug. Closing verified+fixed. |
