When you disconnect a CardBus Compact Flash (CF) adapter, your Windows XP computer BSODs in Pci.sys:

A problem has been detected and Windows has been shut down to prevent damage to your computer...

Technical information:

*** STOP: 0x0000007E (0x........, 0x........, 0x........, 0x........)

This behavior can occur if you remove the CardBus adapter after performing a file transfer, or editing a file on the CF card.

NOTE: If you wait a few minutes after the transfer and you still get a BSOD when removing the CardBus adapter, you will have to wait until Microsoft corrects the problem is a future hotfix or service pack.
