Testing with another kernel will have to wait until > next Thursday as that is when I'll next have physical access to the machine. A bug has been opened at bugzilla.kernel.org as requested. The logs, kernel configuration and the "lspci -tv" output (requested in a subsequent email) have been added. The logs and kernel configuration are from the kernel.org 5.15.139 kernel. You have been added to the bug's CC. The bug number is 218268: https://bugzilla.kernel.org/show_bug.cgi?id=218268 As mentioned, testing another kernel can only happen next Thursday. If you would like other tests done let me know and I'll do them at the same time. I have remote access to the machine, so it's possible to retrieve information from it at any time. Let me know if there's anything else I can do to assist. Regards jonathan
