[tulip] stall on tulip card
Tue, 20 Feb 2001 07:58:55 -0600 (CST)
Just a followup to this thread:
I had been experiencing regular (daily) lockups on the ethernet
port my Linux when running X clients on a WinY2K box. They
started after I began running SETI@home on both boxes.
I downloaded and have been using this driver shortly after its
release and have not experienced a lockup since then. So it
appears to have solved a problem for me.
Let me know if you want further information om my setup.
