In order to eliminate this problem I switched back to MBR yesterday, because so far I haven't received any instructions or guidance as to how I can debug it further. I'm absolutely sure USB write speed is just another manifestation of it so I decided not to debug USB specifically (it just doesn't make too much sense). What I see is that something terribly wrong is going on but if Linus has no ideas I, as an average Joe, don't have a slightest clue as to what I can do. The bug report with necessary, but seemingly useless information, can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=53551 If anyone comes up with new ideas I can quickly try UEFI again now that I have two HDDs at my disposal (the old one is formatted as GPT, the new one is MBR).
