Having read the "How to report a problem" page you linked to, I think I need to do a little more research before submitting a bug report.
One thing I did notice is that when apm is enabled, the output of
dmesg contains the line:
Code:
cbb0 at pci0 dev 10 function 0 "O2 Micro OZ69[17]2 CardBus" rev 0x00: irq 11
But when apm is disabled, that line becomes:
Code:
cbb0 at pci0 dev 10 function 0 "O2 Micro OZ69[17]2 CardBus" rev 0x00: irq 11, Cardbus support disabled
Which would explain the disappearance of ath0, since I'm using a PC Card network adapter. But why would disabling apm also disable support for CardBus?
