Kenneth;
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 reb
ooted.
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 misbehavi
ng 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, everyt
hing 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 flas
h would not work properly in a certain router (2501) but would work just fine i
n other routers is a mystery to me. I eliminated the boot rom chip variable ear
ly on, it is the latest version. So, if you can mix and match your DRAM and Fla
sh 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 elim
inate variables as you work through the problem. And, as with all troubleshooti
ng, try one variable at a time. As I said, it took me two days to try the vario
us combinations before everything worked (2 weeks now.... knock on wood). Best
to you!

Hello Gents and Ladies,
I have 2501 router at home lab that reloads itself.
Here are three error messages generated for different instance of self reload.
1. System restarted by bus error at PC 0x3196CB8, address 0x108E0C 233 0930
2. Parity (control reg=0x8318) Error, address: 0x133604 at 0x3185E56 (PC)
3. Parity (control reg=0x8318) Error, address: 0x13B750 at 0x3196CB8 (PC
Since the third one above the sh ver display has comment
System restarted by bus error at PC 0x3196A0C, address 0x16760C.
Here is the sh ver since last reboot

It will do so while unattended. But also particularly when a save to running or
save to start is performed.
Any one have an idea what the problem might be?
Making use of th ethernet and serial o ports. Running ip, ospf, bgp and ipx rip
.
Thank you for any support.
