[Bug 525174] Re: WARNING: at /build/buildd/linux-2.6.32/net/ipv4/tcp.c:1452 tcp_recvmsg+0xb08/0xbc0()

[George]

Hi,

I can reproduce this on 10.04.01.

$ uname -a
Linux newslut 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 05:14:15 UTC 2010 x86_64 GNU/Linux

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

The board is a Gigabyte ga-d525tud.

I see the following messages about 4 or 5 times and then the box will
completely hang and need a power cycle to restore it.
