Panic in a recent kernel (cardbus/pci related ?)

[Thierry Herbelot]

Hello,

I'm seeing a panic in my latest -Current kernel (config file == GENERIC minus 
INVARIANTS, WITNESS and SMP). The machine is an older notebook, with a PCMCIA 
network card.

The end of the verbose dmesg, showing the panic is following :
