<BR>
Thanks for the quick response!<BR>
I’ve applied the patch but I’m still getting the problem.<BR>
I’m progressing the diagnosis with printk() etc, and will update this post if and when I get any further.<BR>
<BR>
Thanks again.<BR>

This might be related to a problem we've fixed about a month ago in the<BR>
upstream kernel:<BR>
<BR>
<a href="https://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=58af19e387d8821927e49be3f467da5e6a0aa8fd">https://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=58af19e387d8821927e49be3f467da5e6a0aa8fd</a><BR>
<BR>
The fix made it into Linux 3.1. Can you somehow give it a try?<BR>
(Backporting to your F14 kernel should be fairly trivial, since it's a<BR>
one-line change in tcp_minisocks.c.)<BR>
