Weird; that line comes from drivers/net/phy/phy.c in
phy_print_status(), and it's just a a pr_info statement. I suppose it
might be a stack overrun, but I'd expect more severe symptoms if that
was the case.
That *looks* like a serial stream corruption. Is that the output of
your serial port? Does dmesg show the same corruption?
Cheers,
