Looks like it comes from the SDHCI controller ? Any idea what might be wrong ? I get the same oops with kernel 2.6.34, so this seems to be a long existing issue.

Hi,

I get the following kernel-oops during boot process:

dummy regulator

With CONFIG_REGULATOR_DUMMY, every MMC host controller on the PCI device tries to create the same dummy regulator. You could try deselecting CONFIG_REGULATOR_DUMMY.
