serial console corruption

Subject: serial console corruption

        I've gotten Linux 2.2.1-dec + my patches starting up on a
DS5000/200 as far as a root mount, however my serial console is horrible
corrupted, if I leave in the second printout through the prom the kernel
messages are readable from that, but still the serial direct ones are
crappy ..
note in the excerpt below how the second lines are always corrupted, these
are the lines printed by the serial driver, while the first lines are the
ones from the prom,

Does this happen on all Decstations or is just mine, i.e. is someone else
fixing this or have it fixed?
