CardBus Locks PC

Wireless Lan cards lock up my older Vaio notebook when inserted, control

returns when removed. Details:

TI PCI-1420 CardBus Controller ver 5.1.2600 (2001)

XP home SP2

ACPI - IRQ sharing - PCI devices all share IRQ9

I sure acts like a resource sharing issue, computer is fine if I diasble the

drivers and then insert a card. I've never use these slots, so it may be a

hardware issue.

I've updated to the newest bios I can find and have a clean XP install. I

can't find a newer 1420 driver and it seems this is a very common driver at

that.

Have no idea how to diagnose this any further. Any suggestions are greatly

appreciated.
