The other way round, I am getting the impression that other changes are getting stacked on top of the faulty ones, further complicating the picture. As of today, with kernel 6.11.11, the issue has /worsened/ for me. On 6.11.4 I could hibernate/resume by kfkilling bluetooth only, which was not so bad, since I only use bluetooth rarely. With 6.11.11 I need to rfkill the wlan too. Can this be confirmed too? Sergio
