hello osama,

you said you had a crash with 12.2(7)a, which may be related to an IOS
software bug and changed IOS to 12.3

I would have chosen to upgrade to the latest 12.2 image which I believe must
be around 12.2(25) or so by now.  Ive had a 7206 on 12.2(19) running for a
long time without issues.

also what features are you running on the box, perhaps you can identify
which features are triggering the crash ?

IMHO 12.3 may be still abit too new, and has many new features, and
therefore new bugs, especially for production network.

We have a 7200 that keeps on crashing, giving the error "System returned
to ROM by bus error at PC 0x80007D98, address 0x7DE8 at 12:13:17 AST Sun
Oct 10 2004".
I couldn't find anything on the web or Cisco's site and tools to explain

We were running IOS 12.2-7a, when it a crashed a couple times and
couldn't find any reason, I thought there might be an undocumented bug,
so I set it to load 12.3-5d if it crashes again. It crashed again and
took on the new IOS (12.3-5a.) And it also crashed twice when running
the 12.3-5d.
