pccbb pccard rman - Something is very wrong somewhere

Hello,

I have been trying to find this exact bug but I have been unable. Any help
would be apreciated.

Using 5.2-Current

Problem related to pccard using NEWCARD (OLDCARD works ok), not reading
CIS.
Googling I have found some reference:
http://lists.freebsd.org/pipermail/freebsd-mobile/2003-December/002611.html

Activating debugs I find something really weird:

1. cbb1 allocating from beginning??
allocating from the beginning
2. size 0x6bffe000????
truncated region: [0x88002000, 0xf3ffffff]; size 0x6bffe000 (requested
0x400)

If, _after boot_ , I change value hw.cbb.start_memory to 0xd0000000:
hw.cbb.start_memory: 3489660928
PCMCIA works.

I have been investigating the issue in subr_rman.c, as I have showed that
cbb resourses are the only that hit "region is allocated" and success after
it, but I haven't found the problem.

Here are some logs:
