(I have not followed this thread from the beginning so please excuse me if I have missed something) I do not think this is an alignment-related error. The cbb only wants 4096 bytes so why must it be aligned on bigger blocks. What you do are that you disqualify the address rman chooses on your system, what is bad somehow. I had maybe the same problem when I first upgraded from 4.X to 5.X. Can you check if some other device also have got the same memory area assigned (later in dmesg)? The problem for me are that when memory for the pccard gets allocated FreeBSD takes the next available memory but dont check the list of reserved memory areas that it got from BIOS before, and actually it allocates the memory that BIOS has wired to my fxp0 device that is initiated after my cbb. So I have to set hw.cbb.start_memory in /boot/device.hints to a memory area that I has beforehande confirmed that it is free (4096-aligned) -----Original Message----- From: "Carlos Velasco" <freebsd_at_newipnet.com> To: "M.
