Still dies in serport_ldisc_write_wakeup (doesn't matter how to trigger)
via:

Unable to handle kernel NULL pointer dereference at virtual address 00000068
EIP: c020294f
	tty_wakeup
	uart_close
	wait_for_completion
	release_dev

If you want me to be more specific, wait until I figure out how to print
only parts of oops (to fit them on console).
