>Description:
I have a Cardbus 3 port USB 2.0 adapter, this particular device is a conceptronic CSP480C3.
On a ThinkPad X60s booting the 7.99.39 or 7.0.1 i386 kernel, connecting the card and once the kernel has detected the device with the ports attached, ejecting the card, results in the kernel reporting errors. The system eventually reboots by itself.

Output below is from attaching the card, proceeded by connecting a USB adapter to ensure a port is functioning before the card ejected again.
