We were trying to upgrade a 2100A from 3.2G to 4.0D. At the halfway point
it needs to be upgraded to 4.0A. We had upgraded the firmware using the
5.3 disk (eventually we were going to 4.0E). When the upgrade finished to
4.0A the machine would panic when trying to initialize the SWXCR-EB board
streaming an dump on the console. The SWXCR at that point was running
firmware rev. 2.15. Assuming we needed to upgrade the firmware to 2.16 we
eventually did that but still had the panic. It would panic booting either
the 4.0A kernel on disk or the CD-ROM ending with a Severe Machine Check
(660) error.
Time being short we restored 3.2G and the machine booted fine. It would
also boot the 4.0D CD-ROM fine. When we called Compaq the software guys
hadn't heard of the problem and said that it was probably a hardware
problem. The hardware guys said it was strange that it would boot with
4.0D and 3.2G but not 4.0A and that if the board were broken it should boot
anything.
Other picky details: It's got 3 KZPSA boards in it and it's a 5/250 with
1.5GB of memory. The SWXCR is the only SWXCR and it's a 3-channel board
with 4 disks ea on two of the channels.
Any clues out there? We ended up doing a fresh install on this machine but
we have three other 2100A's running on a production system we'd much rather
upgrade than do a fresh install and have to reconstruct.
