Hi,
After upgrading from the 4.19 kernel to 4.20 my usb wifi stick doesn´t
work until I reboot the system(the problem occurs when the system was
shut down).
Dmesg shows the following error when the issue occurs:
xhci_hcd 0000:15:00.0: WARN Set TR Deq Ptr cmd failed due to incorrect slot or
ep state.
I´ve already tried disabling iommu and I also tried reverting all
rt2800usb commits that were made between 4.19 and 4.20, but this didn´t
solve the issue, so it´s probably usb/xhci related.
I´ve attached two dmesg logs(one before rebooting, one after rebooting)
here: https://bugzilla.kernel.org/show_bug.cgi?id=202541
Any idea how to fix this?
Thanks in advance,
Bernhard
