Package: linux-image-amd64
Version: 6.1.38-4
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
I start the system and it runs for some time. After some time the backside
USB-ports stop working.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Use the mouse and keyboard for some time. Then after a while they stop working.
In dmesg there is this error:
xhci_hcd 0000:05:00.0: WARNING: Host System Error
which is this from lspci:
05:00.0 USB controller: VIA Technologies, Inc. VL805/806 xHCI USB 3.0
Controller (rev 01)
As a workaround I got the system running normal with
just disable iommu in bios and add "iommu=soft" in grub commandline
I have an Intel i7-5820K CPU and in Bios this is the VT-D in overclocking
section.
My mainboard is MSI X99A SLI PLUS.
With bullseye I did not have this problems.
* What was the outcome of this action?
Without the workaround Mouse and keyboard of backside USB-ports stop working.
With this workaround the work normal.
* What outcome did you expect instead?
Mouse and keyboard of backside USB-ports work for complete uptime of the system.
