You mean 1 Gb each, right?

Not relevant.

Ok, judging by the oopses this time, most of them are in handle_irq and "nosmp" disables IO APIC so things start to point at something irq handling related, if I would have to guess.
Hm, ok, can you rebuild that 3.5.2 kernel with the following options enabled:
CONFIG_DEBUG_KERNEL CONFIG_DEBUG_SHIRQ CONFIG_DEBUG_OBJECTS CONFIG_DEBUG_PREEMPT CONFIG_PROVE_LOCKING CONFIG_DEBUG_BUGVERBOSE CONFIG_DEBUG_INFO CONFIG_DEBUG_VM CONFIG_DEBUG_MEMORY_INIT CONFIG_DEBUG_LIST CONFIG_DEBUG_RODATA
Those are all under "Kernel Hacking". Then boot this new kernel and catch the whole dmesg up and including a couple of oopses and send them to me.
But do not boot with "nosmp" - we want to see whether default SMP kernel still triggers.
This should be for now.
Thanks.
