ERROR: Last Trap: Instruction Access Exception




If you got above error messages when powering on Sun Server (T-series, T1000/T2000), and the boot process stuck in there, do not call Oracle support or open SR via MOS unless you try below simple troubleshooting step:

Try to unplug all USB devices - ie USB keyboard + mouse, KVM etc, then connect your laptop/PC to server via serial port then reboot the server. IF the error messages are disappeared, I believe the server will able to boot as usual.

This issue are mostly related with USB keyboard /mouse or other USB related devices. It could be the USB devices or the USB port of the server it self. Try to plug the USB device on another port then reboot the server again. For T2000
there are 4 USB port on the back and 2 USB port on the front.
