Unfortunately the new BIOS still has the DMAR bug: [ 0.050968] DMAR: [Firmware Bug]: Your BIOS is broken; DMAR reported at address 0!

A big thank you goes to wink as he has been doing extensive debugging and found the workaround to disable M3 MHI state. Great work! Though I doubt we can upstream the MHI workaround so we still need to find the root cause for the problems with 1 MHI vector patch. So expect more testing requests from me in the future :) But I have now ordered Dell XPS 13 laptop and I should get it in three weeks, keeping fingers crossed. That should make things easier as I can test patches myself. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches -- ath11k mailing list ath11k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath11k
