 Hello,
 
 I am running NetBSD 4.0 Beta 2 on an otherwise Netbsd-3
 system -just installed the kernel to test it.
 Though this may not be the most correct setup, it should not effect the
 interior of the kernel, IMHO.
 
 I can still repeat the rtw0 messages described in the PR.
 
 On a separate 4.99.19 installation (different partition) I only
 got one "tx fifo underflow" while running cvs update of
 sys and common over that link, i.e. causing some traffic.
 
 So, is there a fix that was not pulled back to 4.0?
 Or is this just the sideeffect of something different?
 
 
 Regards,
 
 Rudi
