So the problem didn't occur JUST after the upgrade. But it never occured before it, while we were using older kernels (varius 2.6.30.x, 2.6.29.x and older). I've updated machine to 2.6.31.5, and it's been running without problem since then, but it's been just few days, so we'll see. I'll report if the problem appears again.
