>Description:
USB 2.0, 40 MB/s
cp to a 8 GB CFcard, 18 MB/s, Sandisk ImageMate

After a lot of files the cp hangs.
The light changes to red continously.
After about 1 minute the light changes to green.
After about 3 minutes the kernel becomes panic
and reboots automatically after 15 seconds.

In BIOS I have changed from Highspeed to Fullspeed.
The usb connect message shows 40 MB/s again.
..

>How-To-Repeat:
copy again.
>Fix:
USB Fullspeed?
