I didn't get the start of this thread, but I have seen bugs at
page_alloc.c:131 and :117 with a "stock" 2.4.19-pre10-ac2. It not really
Alan's version because I have Chris Mason's reiserfs logging patches, a
BSD super.c fix and the bridge-netfilter patch.

The bug usually strikes at shutdown of the X server, and I have yet to
see this with the opensource nv X11 driver.

Is providing Nvidia with information do any good? Do they respond to bug
reports and actually fix bugs? It might be that they just need to track
new VM behaviour, but I can save the time of writing a bug report if
it's either no good or if someone already did.
