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 shows this morning:

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.
