As others have noted, Tor's patch appears to be a total solution to the
recent instability the PAE patch introduced. So, if you're experiencing
panics with a recent kernel, or are in a position to stress a machine,
please cvsup and give it a test!
Thanks,
Mike "Silby" Silbersack

Avoid conflict between temporary page table mappings performed by
interrupts and temporary page table mappings performed outside
interrupt context without splvm() protection. Interrupt time async
completion callbacks for pageout operations triggered this conflict.
