Hi, I am trying to use the "ppc-soc-ohci" driver on a redwood5 based board w/ kernel 2.6.17-rc1. It's not really inspiring confidence, because I get tons of messages similar to these

Since it _seems_ to work nevertheless - is CONFIG_DEBUG_SLAB known to be broken on this platform? (Although such stack traces are only printed when doing sth with the USB). Or is this caused by some other (memory initialization?) error? Greetings, Andre'
