hi

i am getting the following error scrolling continuously
in my dxconsole:

        UBC write error(28) on device(0,0) at block 16 size 8192
        UBC write error(28) on device(0,0) at block 32 size 8192
        UBC write error(28) on device(0,0) at block 48 size 8192

i am on a dec alpha 200 4/166 running digital unix v3.2.
the monitor is a 19" digital vrc21-ha

the device(0,0) seems to be the monitor - according to
an ls -l in /dev. i have only noticed one wierd display
problem when the display did not refresh a text file properly.
i am actually sending this from the computer with the error
message.

as a side note, we recently temporarily put in a zlxp graphics
card, but it didn't do what we wanted it to so we are back to the
original card.

any clue as to what this error is, how to fix it and where to
decode other errors would be greatly appreciated!

thanks
