Description davestg 1999-07-18 05:40:01 UTC

FreeBSD will completely lock up if I connect from the windows machine.  The problem seems
random, but I haven't been able to keep an uptime of more than 3 days.  I have
ipfw and natd as well as ppp running, and the internet link works MOST of the time.
However, recently, FreeBSD has crashed during normal use of natd and ipfw.  I 
can't be exactly sure as to where the problem is because there is no information
on the console at the time of the freeze, and there is no indication in any logs.

Fix: 

Don't connect to freebsd with the windows machine.  Everything works fine on
the FreeBSD side when connected to the internet; it only crashes at certain times
when connecting from windows (or any host?  I might boot up with PicoBSD on the
Windows machine and hammer it...)
How-To-Repeat: Connect via telnet or ftp from the windows machine.  Various events have triggered
a freeze including "more", transferring files to FreeBSD from windows, sending 
mail to sendmail which gets bounced back, accessing POP too many times, trying to use
Apache as a proxy for more than 1 minute, accessing a web page.

I consider this report closed.  The fix was in the BIOS.  I had to
disable the PCI burst settings, and now everything works fine.  The
settings worked under Linux, but I guess the de driver under FreeBSD
isn't as forgiving.  Thanks to all that helped.
