You mentioned this was an HP rx2600. You can tell for sure whether it was an MCA (and get useful information about it) by doing "errdump clear" at the EFI shell prompt before reproducing the problem, stopping at the EFI shell prompt again during the subsequent reboot, and doing "errdump mca". There's also a "salinfo" package that automatically retrieves and logs this information. It's part of Debian, there are sources here: ftp://ftp.kernel.org/pub/linux/kernel/people/helgaas or I can send you an RPM for RHEL3 if you need it.
