serial console seems to change baud only in single user mode?

has anyone seen something like this or know where to fix it?

machine: v880
solaris 8
sun cluster 3.1
OPS (so udlms)
vxvm 3.5

when i try to boot this machine -sx it always produces nonascii after
"VxVM general startup".
I believe it has switched baud rate on the serial port because i consistently
get a y with two dots over it whenever i hit return.
i tried rebooting our terminal server, but the problem seems to be on
the v880 because
the behavior remains the same until the v880 is power cycled. then
everything is normal,
unless i do a boot -sx. after VxVM general start, it goes into
gibberish mode again.
what is interesting is that boot -x works fine, it boots all the way
up with no complaints...
however..when i do init s...it comes down and then goes in the the
same gibberish mode
where returns produce y's with two dots over it. hoping someone might
have some insight into this behavior...

here's an example of boot -sx
ok boot disk works!!
boot -sx does not still
Rebooting with command: boot -sx
Boot device: /pci@8,600000/SUNW,qlc@2/fp@0,0/disk@w21000000871a4235,0:a
