2.6.25-rc8: WARNING: at net/ipv4/tcp_input.c:2173tcp_mark_head_lost+0x11d/0x150()

From: Soeren Sonnenburg
Date: Thu Apr 03 2008 - 01:11:28 EST


trying to download things, I am seeing this (ignore the tainted, it is
from madwifi and although the module is loaded the device was never
used)

Could anyone make sense of this please?

Thanks,
Soeren
