disable_irq() causes hang on AT91RM9200 targets?

Guys:


Has anyone noticed that with 2.6.33-rc5 (at least) on AT91RM9200,
disable_irq() seems to cause a lockup when the interrupt number is a
GPIO line?  I'm calling disable_irq() from an interrupt handler on the
same GPIO line.

I just saw this happen, and it seems to be repeatable.  Just wondering
if this is a known issue before I start digging into it...


b.g.
