2.6.13-rc6-git5 : PCI mem resource alloc failure

2.6.13-rc6-git5 : PCI mem resource alloc failure

[Parag Warudkar]

With 2.6.13-rc6-git5 I started getting the below errors. Despite of the
errors everything works fine. (only problem is that I have to
disconnect /reconnect the usb mouse for it to get detected..)

Another problem is that PCMCIA is busted - I get the below errors and my
wireless pcmcia card no longer works with -rc6-git5.

Starting PCMCIA services: cardmgr[2929]: watching 2 sockets

cat /proc/iomem before you modprobe the module - is 20000000 already reserved 
by the motherboard?
