Anyone know where to find the release notes for the various ROMMON versions for the 2800 and 3800 routers?  Noticed 'DRAM access optimization' as a benefit of the latest 2800 ROMMON, and I recently worked on a problem with a 3845 giving console messages like this:

I've got a feeling it's really bad hardware, but usually want to exhaust all the possible bugs before calling TAC.  Since it specifically mentions ROMMON variables in the output, figured it was at least related.  The DRAM access optimization thing just sounds interesting.  Searched the web site for a good 20 minutes, no luck.

Thanks,
