2.6.x kernels & PCI-to-PCMCIA bridges [again]

[Dominik Brodowski]

That's a real strange panic() -- and even more strange, I do see the exact
same panic() [call trace starting at common_interrupt(), Process pci.agent()
for me] on some occasions when I use the new Intel driver for the ipw2100
WLAN Mini-PCI card -- which also uses parts of "hostap". Also, nothing in
the call trace does seem to be pcmcia-related... Does anybody have any
ideas on what the cause of these panics might be?
