    Unfortunately, latest linux tree doesnt even boot on my machine, so I
    cannot reproduce the problem right now.

    Last message displayed being "Switching to clocksource tsc"

    Previous kernels were continuing with :

    [ 4.448417] 00:09: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
    [ 4.597727] Real Time Clock Driver v1.12b

    Might be a problem with latest tty changes
