On the kernel built on December 17 (not necessarily -CURRENT as of
December 17) card works properly. Here are dmesg bits from card
insertion:
Status is 0x30000821
cbb0: card inserted: event=0x00000000, state=30000821
cbb0: cbb_power: 3V
Interrupt storm detected on "irq10:"; throttling interrupt source
cardbus0: Non-prefetchable memory at 88000000-8800ffff
ath0: <Atheros 5212> mem 0x88000000-0x8800ffff irq 10 at device 0.0 on
cardbus0
ath0: Ethernet address: 00:0c:41:dd:c7:0d
ath0: mac 5.6 phy 4.1 radio 3.6
Cardbus controller is:
cbb0@pci0:10:0: class=0x060700 card=0xc60214ff chip=0x69721217 rev=0x00
hdr=0x02
vendor = 'O2 Micro Inc'
device = 'OZ6912/711E0 SmartCardBus Controller'
class = bridge
subclass = PCI-CardBus
PCMCIA-to-CF adapter does not cause Fatal trap.
If there are any other bits of information I can provide, please, let me
know.
