I just upgraded a Sony Vaio Z600 laptop from 4.2 to 4.4.  Under 4.2 I
had to set the pcic irq to 9 (rather than 0, polling mode) otherwise
inserting any card would hang the machine.  I got the value "9" from
what Windows has.  I was able to use both my Wavelan card and CDROM
in this way.

Under 4.4, my Wavelan card works in the default mode (though I once
had a problem when I unplugged it), but the CDROM (which uses an ATA
pc card) hangs it.  It doesn't help to set hw.pcic.intr_path to 1
and hw.pcic.irq to 0.  I tried to obtain the old setting - ISA routing
and an IRQ - by setting hw.pcic.intr_path to 1 and hw.pcic.irq to 9,
but that produces a panic during boot:

pcic0: <Ricoh RL5C475 PCI-CardBus Bridge> at device 12.0 on pci0
pcic0: PCI Memory allocated: 0x44000000
pcic0: Can't route ISA CSC interrupt.
panic: resource_list_release: can't find resource

The boot messages under 4.2 were:

pcic0: <Intel i82365> at port 0x3e0 iomem 0xd0000 irq 9 on isa0
pcic0: management irq 10
pccard0: <PC Card bus -- kludge version> on pcic0

Any suggestions?
