Subject: Regression xhci_hcd cmd failed due to incorrect slot or ep state
Date: Sun, 7 Apr 2019 12:32:33 +0200 [thread overview]
Message-ID: <0d300c86-4aaa-28d4-cb37-5bc62fa67a9a@gmx.at> (raw)
When using the kernel version 4.20 or above my usb wifi stick doesn't
work until I reboot my system, dmesg shows this message 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 found that the problem is caused by this commit:
commit f8f80be501aa2f10669585c3e328fad079d8cb3a

xhci: Use soft retry to recover faster from transaction errors
It looks like it only affects wifi sticks(various models) on specific
hardware configurations(I have this issue on my Ryzen pc, my Intel pc
isn´t affected, but someone in the kernel bug tracker mentioned that he
has this issue on an Intel notebook as well (only with USB 3.0 ports
though)).
