Hi, +Cc Christoph Hellwig Christoph, this is still an issue, so I've been looking around a bit and think this might have something to do with the dma-mapping-5.10 changes. Do you have any suggestions to debug this, or is it time to do a git bisect on this before 5.10 ships with regression?

5.10 regression, many XHCI swiotlb buffer is full / DMAR: Device bounce map failed errors on thunderbolt connected XHCI controller

Hi All, Not sure if this is a XHCI driver problem at all, but I needed to start somewhere with reporting this so I went with: scripts/get_maintainer.pl -f drivers/usb/host/xhci-pci.c And added a Cc: linux-...@vger.kernel.org as bonus. I'm seeing the following errors and very slow network
