Comment (by anevilyak):
Replying to [comment:9 kallisti5]:
> Is this a "multi-cpu-smp" issue or strictly a "hyperthreading cpu"
issue? SeanCollins, do you have a Pentium 4 HT cpu, or a multi-core cpu?
As another data point, quad core w/ hyperthreading here (ergo 8 CPUs
visible to the OS), and I've never seen this under all kinds of punishing
workloads. That having been said, 8GB of physical RAM is available, so if
it's the low memory condition triggering it, then I'm not easily going to
hit that. However, if Ingo's theory about something else overwriting the
page tables is correct, then it seems plausible that a particular
misbehaving driver in your case might be triggering it, else one would
expect it to be much more widespread. The type of CPUs involved really
doesn't have much to do with how the memory mapping's handled per se
(excepting the obvious availability or absence of PAE), and from a
multitasking standpoint, if anything HT should be less strenuous than true
multicore since the circumstances under which it can multitask are more
limited.
