Hi,
just today I got this error, never had it before in all those
months I have been tracking CURRENT now.
Jun 6 17:15:26 daemon /kernel: sio0: 65 more tty-level buffer overflows
(total 65)
Jun 6 17:15:28 daemon /kernel: sio0: 131 more tty-level buffer overflows
(total 196)
Jun 6 17:15:29 daemon /kernel: sio0: 38 more tty-level buffer overflows
(total 234)
until I interrupted it with CTRL-ALT-ESC to drop into DDB.
This is some info I got from DDB:
[ please bear with me if I didn't get all I need, but it's the first
`crash' I intercepted and I think I got all the relevant data, comments
appreciated though ]

I also have results from show registers, print, show page if those are
deemed interesting.
What I was able to glance from ps what that the 0xc5b6dfe0 range lay in
an xterm memory range... I am not 100% sure about this though.

The system itself is a simple DFI-based motherboard with Intel Pentium 200 MMX
and 96 MB RAM.
The keyboard is not one of them ps/2's, but a the older type (I don't think
that DIN is the correct name though).
the device on sio0 is my serial MouseMan:
controller isa0
controller atkbdc0 at isa? port IO_KBD
device atkbd0 at atkbdc? irq 1
device vga0 at isa? port ? conflicts
device sc0 at isa?
If any more information is required, please tell me and I will see if I can
dig it up.
'gards,
