Allocate aligned memory

[Marc Lörner]

Hello all,

I want to allocate 120KB of memory thats aligned to 32KB.
I already saw/found the function contigmalloc, now my question is, why 
following functioncall never does return with an resulting address, instead 
null is returned?

unsigned long *p = (unsigned long*) 
	contigmalloc(120*1024, M_DEVBUF, M_WAITOK, 0, (1<<22), 32*1024, 1024*1024);

Thanks in advance,
Marc

P.S.: I'm already aware that contigmalloc doesn't support M_WAITOK!
