Hi All!

I'm getting these occasionally on my 3.4STABLE box here:

xl0: transmission error: 90
xl0: tx underrun, increasing tx start threshold to 120 bytes

But it doesnt seem to cause too many problems.

However, I get them all the time on another box running 3.4-RELEASE
which is a Samba server.

If someone hammers the server (usually by running a backup from a Win 98
workstation) it will reliably generate loads of the above error, then
lock up solid.

The two machines are quite different, the one with the mild symptoms is
a Celeron 466 w 256MB RAM and the bad one is a Pentium 133 with 64MB RAM
on an Intel HX chipset.
