[BUG] unable to handle kernel NULL pointer dereference

From: John
Date: Sat Feb 15 2014 - 07:18:15 EST


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.
