: network drops dead after putting interface in promiscuous mode

Hi

I have a problem with the test8 version of the 2.6.0 kernel. After i changed the network to use DHCP instead of an static network adress. I have internet access until i use tcpdump, ethereal or snort ... because when i do this then something seems to crash i have no connection at all anymore. Sometimes even my computer completely freezes. When that happens i only can use the reset button for an forced reboot.

I use: Debian (sid)

i once tried to remove the module from the kernel and wanted to insert it again, hoping this maybe would help ;-). But this also resulted in a complete freeze of the system and i had to do a forced reset again. The error-message from that crash was:
