I'm back to trying to get my laptop working with both it's cardbus
slots again....

I tried the latest 2.4.18-pre7 + mppe(VPN) + Jes Sorenson's
IRQ routing patch for certain VAIOS.  Jes' patch was recently
posted to LKML, but it does not seem to affect my problem...

However, the same problems I was having with the 2.4.6 kernel
a while back are still here.  When I insert an adapter in the
second cardbus slot, the machine hangs (alt-sysrq-p does nothing)

I see this when I remove the NIC, and the machine starts working again.
cs: socket c7f90000 timed out during reset.  Try increasing setup_delay.

I believe the problem lies with this:

Linux Kernel Card Services 3.1.22
   options:  [pci] [cardbus] [pm]
PCI: Assigned IRQ 9 for device 00:0a.0
PCI: Assigned IRQ 10 for device 00:0a.1
IRQ routing conflict for 00:07.5, have irq 5, want irq 10
IRQ routing conflict for 00:07.6, have irq 5, want irq 10
PCI: Sharing IRQ 10 with 00:10.0

If I can offer any more debugging information, don't hesitate
to ask!

The full dump of lspci -vv, and dmesg is attached.  dump_pirq.pl
shows this:
