Mikolaj,
Thank you for testing my patch.
I am very interested to know what xhci (or ehci) hardware you have.
I have the following:
xhci0 at pci0 dev 20 function 0 "Intel 9 Series xHCI" rev 0x03: msi, xHCI 1.0
usb0 at xhci0: USB revision 3.0
uhub0 at usb0 configuration 1 interface 0 "Intel xHCI root hub" rev 3.00/1.00
addr 1
ure0 at uhub0 port 14 configuration 1 interface 0 "Realtek USB 10/100/1G/2.5G
LAN" rev 3.20/30.00 addr 3
ure0: RTL8156 (0x7030), address 00:e0:4c:ab:64:5a
My ure0 is https://www.amazon.com/gp/product/B07Z8S6PN4
<https://www.amazon.com/gp/product/B07Z8S6PN4>
I do not get any watchdog errors with this.
Kevin has been testing my patch and giving me good feedback. He has seen some
watchdog errors with an RTL8153B also.
I am starting to suspect that I have the tx xfer size wrong (too big) for the
8153 / 8153B devices. I am also trying to eliminate the XHCI hardware as a
cause.
Please could you post your dmesg? At a minimum it would help me a lot to see
your usb hardware.
Thanks,
Jonathon
