3COM 905XL tx underrun?

[Attila Nagy <bra_(_at_)_fsn_(_dot_)_hu>]

Hello,

I have a machine with OpenBSD-CURRENT (5. oct) running on i386
(Athlon-750).
The NIC is a 3Com 3c905C card.

The problem is that the machine writes occasionally the following:
xl0: transmission error: 90
xl0: tx underrun, increasing tx start threshold to 120

What is this and how could I fix it?

Thanks,
