Re: 3825,System returned to ROM by bus error HELP!!!!

Bug, change to a more stable IOS.

T versions are very buggy.

Re: 3825,System returned to ROM by bus error HELP!!!!

The router must have spawned a crashinfo file when it rebooted. If you can get me that, I can try looking for known bugs and un-affected IOS versions
