* [2.6.37/38] SDHCI spurious interrupt...

With 2.6.37 (and by extension 2.6.38-rc1, as the code hasn't changed),
I occasionally see an 'IRQ 16: nobody cared' message a second before
shutting down (previously reported [1]); the culprit is the SDHCI
driver for my Ricoh controller.

I modified the interrupt handler to be unregistered later with a
delay, and to dump out the interrupt mask read, but didn't catch it
yet.

Any ideas?

Thanks,
  Daniel

Are you able to bisect?
