Is this a regression?  Was 2.6.37 OK?

So both sdhci_irq and r852_irq were looking at the IRQ, but neither of
them were interested in it.

Could be that the bug lies in neither driver, at that something went
wrong with the system setup.  ACPI?

Currently I cannot reproduce it, with or without acpi. /var/log/messages

When it comes back I will try to reboot with acpi=off.

I don't see anything that would implicate the MTD layer at all.  SDHCI
is unrelated to MTD.  Just an FYI.
