Subject: Invalid opcode on resume from STR on Asus P4P800-VM

Hello,
I'm trying to debug oops on resume from suspend-to-RAM on Asus P4P800-VM
mainboard. It crashes with invalid opcode (see below). The kernel is 
2.6.32-trunk from Debian but the same problem is present with vanilla
kernels - both newer and older (but screen remains blank most of the time,
only keyboard LEDs blink indicating an oops).

What can cause this problem?
