Maybe as a last ditch effort try dynamic debug, if your kernel supports it: echo 'func xhci_dbg_trace +p' >/proc/dynamic_debug/control rmmod xhci-pci modprobe xhci-pci echo 'func xhci_dbg_trace -p' >/proc/dynamic_debug/control dmesg |grep 'page size' [ 262.117753] xhci_hcd 0000:08:00.0: Supported page size register =3D 0x1 [ 262.117755] xhci_hcd 0000:08:00.0: Supported page size of 8K [ 262.117756] xhci_hcd 0000:08:00.0: HCD page size set to 4K BTW, don't worry about that 8K, this value is incorrectly calculated and th= en completely ignored. --=20 You may reply to this email to add a comment.
