The patch I mentioned is not included anywhere yet. I was asking if you could explicitly test the patch on top of our packaging, to see if it resolves your issue (I would be fairly confident now if this is the same device). The patch is in message #69, https://bugs.debian.org/1012210#69 . The other thing I did not outline is to actually test a patch on top of the packaging. This can be done with the following procedure: https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#id-1.6.6.4 Does this help? Regards, Salvatore
