--- Comment #1 from Mathias Nyman (mathias.nyman@linux.intel.com) ---
Does preventing xHC runtime suspend help:

echo on > /sys/bus/pci/devices/0000:c2:00.4/power/control 

Could you also collect xhci trace and dmesg with dynamic debugs enabled when
triggering this issue

mount -t debugfs none /sys/kernel/debug
echo 'module xhci_hcd =p' >/sys/kernel/debug/dynamic_debug/control
echo 'module usbcore =p' >/sys/kernel/debug/dynamic_debug/control
echo 81920 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/xhci-hcd/enable
echo 1 > /sys/kernel/debug/tracing/tracing_on
< Reproduce issue >
Send output of dmesg
Send content of /sys/kernel/debug/tracing/trace
