High level problem desciption: I have Thunderbold dock with DP-out, USB por= ts and an Ethernet port. When I plug it in, only the DP port works. When its plugged in before boot, ethernet also works. The USB ports on the Dock never work. dmesg is showing several erros regarding DMAR and xhci, since the DMAR erro= rs are shwing up first is suspect them to be the root cause making the rest afterwards fails also. The error is slightly different between 5.13 and 5.14 5.14-rc7: [ 3.148557] DMAR: DRHD: handling fault status reg 2 [ 3.148561] DMAR: [DMA Write NO_PASID] Request device [0x04:0x00.0] fault addr 0x69974000 [fault reason 0x05] PTE Write access is not set 5.13.12: [ 3.737783] DMAR: DRHD: handling fault status reg 2 [ 3.737790] DMAR: [DMA Write] Request device [04:00.0] PASID ffffffff fa= ult addr 69974000 [fault reason 05] PTE Write access is not set 04.00.0 is the thunderbold controller: 04:00.0 USB controller [0c03]: Intel Corporation Thunderbolt 4 NHI [Maple R= idge 4C 2020] [8086:1137] (prog-if 40 [USB4 Host Interface]) --=20 You may reply to this email to add a comment.
