Steps to take traces and logs: mount -t debugfs none /sys/kernel/debug echo 'module xhci_hcd =3Dp' >/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 trace file grows fast so please copy it as soon as possbile after issue is reproduced. --=20 You may reply to this email to add a comment.
