Hi,

After swapping an old IDE Plextor DVD-RW for a new SATA one (ASUS), 
FreeBSD does not boot anymore and results in a "non-maskable interrupt 
trap" (trap number 19). The computer is constantly rebooting now when it's 
powered on. It runs FreeBSD 11-STABLE.

In the BIOS everything looks fine, the drive is recognized etc. Even 
disconnecting the new drive keeps panicing FreeBSD.

What can I do to make the computer boot again?

Regards,
Marco
