Dirty scache and panic

This is a self-followup to my original post, which has scrolled off
the local newsserver.
A while back, I wrote ...
| Quote: | My Challenge L has a problem.
The machine tries to boot, declares that it has a "dirty scache",
panics, and reboots. Over and over. Repeat until I'm well-lathered.
I would have thought the secondary cache was on the IP25 processor
board, but changing to a different, previously-tested-good IP25 board
doesn't change things.
This happened once before, but a general cleaning and re-seating of
everything fixed it, at least for a couple of weeks.
Is it possible that some software is causing this?
If not, where is the secondary cache and what can I do about this?
Machine specs: Challenge L deskside, 1 four-processor IP25 (R10K), 2
MC3 (totalling about 3 GB RAM), 1 IO4.

.... even though about 99% of the zillion error messages the thing
produced had nothing to do with memory, it turns out that swapping out
the MC3 boards has fixed the problem.
I had error messages point to dirty scache, D-chip timeouts, SCSI
timeouts, missing SCSI devices, you name it. All bogus.
It was the MC-threeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!
