----- Original Message ---- I just loaded haiku image in QEMU and when the system was loading, it crashed into the KDL with this message: PANIC: free: asked to free invalid address 0xdeadbeef Its a joke, isn't?

IE to indicate an uninitialised variable, pointer etc. Other popular values are 0xcafebabe, 0xb00bbabe, 0x1234567 ... :) euan. </lurker mode>
