Subject: [BUG] unable to handle kernel NULL pointer dereference
To: lkml <linux-kernel@vger.kernel.org>

When booting into linux v3.13.3, I am unable to mount an nfs share on this particular hardware. ?I get the same problem using v3.12.11. ?Only the 3.10.x series allows normal operation. ?Partial dmesg output shown inline, additional logs available upon request.

PLEASE cc me on my replies as I am not subscribed to lkml.

Hardware: Athlon XP 3200+ on an NVIDIA nForce2 Ultra 400 motherboard.
Distro: Arch Linux i686.
