Bug 18932

Summary: Total loss of ethernet needing reboot. Possible if_vr driver problem.
Product: Base System Reporter: root <root>
Component: kernAssignee: freebsd-bugs (Nobody) <bugs>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: Unspecified   
Hardware: Any   
OS: Any   

Description root 2000-06-01 05:50:00 UTC 
After an hour or so of traffic on my nic the kernel reports
rx error: unknown rx error.

after that the stack is broken and the machine must be rebooted before
any traffic can leave the machine.

The machine is a PC with a celeron, a DFI M/B with an intel chipset,
the nic is a miibus/rhine compatible DLINK 530TX.  My network is just 2
back to back fbsd boxes. They both have the same DLINK in them but my
second machine is running fbsd 3.4R.  The 3.4 machine has never had 
any problems.

Fix: 

not known.
How-To-Repeat: ~60 minutes of semi-constant NFS(udp), web and other 
misc traffic across VR0

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?

Problem was hardware related; see Audit-Trail for details.
