I can confirm that I'm also experieancing this bug. 12.04, clean
install 16gb ram, 32 swap. It can be replicated in python with:
import numpy as np
l=[]
for i in range(10000):
l.append(np.array(np.ones(10000000), dtype=np.float64))
this can be done in console mode or GUI, the arrays are allocated, ram fills
and swap begins, then the system freezes requiring a hard reboot.
