RE: [Xen-ia64-devel] [PATCH] fixed some bugs to make xen0 more stable

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

In my testing, I now saw what appeared to be an infinite loop
of NaT faults.  The "ps" command showed a "sh" with several
minutes of CPU time while the console window scrolled continually
with "NaT fault... attempting to handle as privop".  This may
or may not be a side effect of the patch I am testing.  I'll
see if it shows up again (but am logging off now until the
morning).
