I had the same issue with an MPC885 board. My kernel was 2.6.33. On that board decrementer exception was not working. I replaced the board, took new board (MPC885 only, just another board) and the same kernel worked fine. I don't know how the problem was solved. -Mohan On 9/22/11, Scott Wood <scottwood@xxxxxxxxxxxxx> wrote: > On 09/21/2011 01:56 AM, Vineeth wrote: >>>> What was the issue?
