Thank you for the comment! Yes, the timer works correct on my environment. echo do > /dev/kmsg; sleep 60; echo done > /dev/kmsg [ 169.784474] do [ 229.791962] done However, the xhci timeout is still about 20 seconds. So, I investigated this issue more. Then, it seemed that readl() in xhci_handshake() is large delay (about 10 seconds) when the xhci driver didn't do firmware downloading.
