Re: Integrity RX2800 i6 MCA Reboot after Panic

Дата публикации: 25-06-2026 19:20:20

Hi,
The MCA files are not very conclusive and we were able to decode only that its a "External Bus error" that triggered all the MCA's.

// You would need to focus on I/O subsystem (IO cards) and see if any of those are causing the reset (isolate one by one and observe system stability).// If still issue persists, then please log a support case with HPE Support Team for further assistance.

Hello, nice to meet you. My system is an RX2800 i6 running HP-UX 11.31 v3 with BIOS version 2.70.
I purchased this model in 2022 and received a motherboard replacement service once through HP Service.
I used it without issues until recently, when it frequently reboots daily or often due to MCA panics.
The warranty has expired, so I am trying to find the cause.

When I search various websites, many suggest that the issue is related to the memory, CPU, or motherboard,
but I would like to find definitive information.

I would appreciate your feedback.
