It occurs mostly at shutdown, or when I have to do a kill on a Smit that has gotten hung. The problem has occurred on both a 320 and a 520 running AIX version 3, and is as follows: The system will go dead, except for the console, which appears to have a debugging screen. At the top of the screen, I get 4 lines which start with GPR0, GPR8, GPR16, and GPR24. These GPR numbers are followed by codes, and the GPR16 has 2 setc of code reading 'DEADBEEF'. I then get a listing of the contents of some registers, and on all 3 systems this has happend on, there follows a dump of memory locations 00028590 thru 000285F0 (it has been this exact same location on all three machines). There is a message at the bottom of the screen saying "Illegal trap instruction interrupt in kernel", followd by a prompt. If you do a quit at the prompt, you have to reboot the system. Has anyone else seen this happen? What causes it, and is there a cure? Thanks in advance.
