Linux is installed in USB3.0 Memory and it operates well when plug in usb 2.0 port.

however, while it is inserted in usb 3.0 port, kernel panic occur.

"cannot open files ko.map"

what's the matter?

When you installed the OS, did you have the usb plugged into the 3.0 port? What OS? Do you see any other info before this?

My guess is one of a few things. One is there are still bugs in the 3.0 booting and running in linux. There may not be full support for the port in the first few files like grub and init files. The usb flash may have some odd issues. Could be that special delays or other timings need to be set to let stuff settle down.

When installing i pluged into 3.0 port, but in install procedure usb memory was not detected. So i retried with 2.0 port..

my os is scientific linux CERN, scientific linux modified by CERN, based on RedHat Enterprise Linux 6.2.

and 'cannot open file ko.map' happen always. this message is not important to solve it.
