Description Anton Troshin 2002-10-09 09:40:01 UTC

   all network interfaces dies after some lagre amount of data transmitted thru one of the NICs. We used fxp and dc NICs. dc dies faster.

Last message in logs is "device timeout". After that machine is fully isolated from all networks.

Fix: 

no idea
How-To-Repeat:    Send some large alount of data thru one of the NICs. I've tried to transfer come hundred megs between two local machines, on 100BaseTX connection, in both full duplex and half duplex modes.

I got the same problem.
It said something like : fxp0: FCB timeout.. 
I use "sysctl kern.polling.enable=0" and upgrade to 4.7-stable, the
problem seems disappear.
By the way, I've checked the source code of freebsd,  I didn't find "FCB
timeout " for device fxp0. what's is FCB? File Control Block?

Hello freebsd-gnats-submit,

  4.7-RC "device timeout" problem

  I've faced with the same problem on 4.8-RELEASE

  fxp0 is Intel Pro 10/100B/100+ Ethernet
  
  I've tried 3 different options:
  no SMP with device_polling
  no SMP without device_polling
  SMP without device_polling

  Each configuration gives device timeout on high packet flow.

Is this still a problem with later versions of FreeBSD? 
Sorry that nobody picked this up in GNATS.
