(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)?=20
The problem for me are that when memory for the pccard gets allocated FreeB=
SD 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)

Hello,
Investigating this problem, I have discovered two issues.
One minor bug (off-by-1) in subr_rman.c:

And the real problem, an alignment issue that prevents pccard to work:

We are aligning to 0x1000 (4096) and we should align to, at least, 0x10000
(65536).
This solves the problem.
Can anyone review these patches and commit them if they are right?
Regards,
Carlos Velasco
