The flood also only starts when udev wants to create its device nodes, meaning the initial detection seems not to produce this problem But when I disable the whole boot partition stuff, it works as before without irq storms. As there don't seem to exist reports from other emmc users about this I guess the problem lays somewhere between the boot-partitions-patch and the sdhci-s3c driver (for s3c2416 at least). As my knowledge about the whole mmc-subsystem is quite spare I also don't really know where to start looking for the culprit yet.
