HP-UX 11.0 System Crash

[Richard Sun]

We have a workstation B2600 with HP-UX 11.0 os. Our application is a factory automation machine. The software is developed in C++ for 10.20. We make some modify to compile it in 11.0 in one machine. Current we are developing a PCI bus Digital IO card. When we run the software, the system will crash. The error message is: Unexpected HPMC/TOC .... After reboot, we get following information from shutdown.log:
reboot in panic, , isr.ior= 0'a607ffd3.c0000000'300d0. Anybody can provide help on this? Thanks a million!

HPMC is a High Priority Machine Check or a hardware fault. You have a hardware issue here.

It appears your Digital IO card created a Machine Check, hence the MC in HPMC. Are you running in 64bit mode or 32bit mode?

when the system reboots there should be a crash dump in /var/adm/crash/
you can use q4 to debug it and get stack traces etc..

hi,

check in /var/tombstones/ts* files.
find out the latest it will have HPMC chasis code.

use q4 and analyze the crash to find out more informatiom.

u can find latest version

As part of Support, we do not want to analyze HPMC dumps using Q4. That method is used for non-HPMC or LPMC panics.

Hardware Support looks at PIM and hardware registers to determine the cause of HPMCs/LPMCs.

You will delay resolution in resolving a HPMC if you run q4 or log a software case first.

We develop the driver (interface) for the Digital I/O card and compile it in 64 bit mode. Maybe the digital I/O card does not support 64 bit mode. Can we compile it in 32 bit mode in HP-UX 11.0? Does HP provide technical support to solve this HPMC panic? Thank you all for your reply!
