I was not able to correct my cbb start memory via an entry in
/boot/loader.conf:
hw.cbb.start_memory=0xc0000000
After next reboot sysctl command shows the correct value in
decimal:
andreas@aklemm[ttyp0]{183} /boot sysctl -a | grep cbb
cbb0: <PCI-CardBus Bridge> at device 1.0 on pci2
pcib2: device cbb0 requested decoded memory range 0xf6000000-0xfbffffff
cardbus0: <CardBus bus> on cbb0
pccard0: <16-bit PCCard bus> on cbb0
cbb0: [MPSAFE]
cbb0: PCI Configuration space:
cbb1: <PCI-CardBus Bridge> at device 1.1 on pci2
pcib2: device cbb1 requested decoded memory range 0xf6000000-0xfbffffff
cardbus1: <CardBus bus> on cbb1
pccard1: <16-bit PCCard bus> on cbb1
cbb1: [MPSAFE]
cbb1: PCI Configuration space:
cbb0: PC Card card activation failed
hw.cbb.start_memory: 3221225472
^^^^^^^^^^
hw.cbb.start_16_io: 256
hw.cbb.start_32_io: 4096
hw.cbb.debug: 0
But the address ranges of bge0 and cbb0 still overlap:
bge0: mem 0xfaff0000-0xfaffffff
pcib2: device cbb0 requested decoded memory range 0xf6000000-0xfbffffff
Here the complete memory ranges in use:
