Kenneth,
The problems this times are caused by fualty DRAM, the first crash occured in a
valid memory address (2MB on board DRAM) and therefore the whole motherboard
will need to be replaced. Up/Down grading will not help the situation.

> I had this very same problem after I upgraded the Flash & Memory on my 2501.
It took me two days to work through, but I "solved" the problem.
>
> 1. I loaded a different IOS which required only 6MB as opposed to 16. Still
rebooted.
> 2. I removed one of the 8MB flash sticks, reloaded IOS, rebooted... Worked
fine....
> 3. I replaced with the other 8MB flash stick, reload IOS, rebooted, worked
fine...
> 4. Tried again with both flash sticks, using 16MB flash, router began
misbehaving again...
> 5. I flip-flopped the Flash sticks in the slots; still rebooted.
> 6. Switched out the DRAM, still misbehaved;
> 7. Switch out the flash once again, using flash from a different router,
everything worked fine.
> 8. Split up the questionable flash sticks and distributed among two other
2500 (2502 & 2511) series, they seem to work...
>
> Moral of the story.... Not quite sure really. Why a certain combination of
flash would not work properly in a certain router (2501) but would work just
fine in other routers is a mystery to me. I eliminated the boot rom chip
variable early on, it is the latest version. So, if you can mix and match your
DRAM and Flash from the misbehaving router with another router you have on
hand, give it a try. Just keep track of the different combinations you try so
that you can eliminate variables as you work through the problem. And, as with
all troubleshooting, try one variable at a time. As I said, it took me two days
to try the various combinations before everything worked (2 weeks now.... knock
on wood). Best to you!
