Confirming. With 2.6.33, I don't get the warnings, but neither get the procfs-entries. Checking my debug-output again, I assume that the hard-disk has the entries, because it is the first user of ide-gd, so that driver still needs to be requested. Maybe this is enough delay for the directories to appear? Wild guess... > Wolfram I'll look into your patch some more and integrate it, thanks.
