Re: Timer interrupt on Linux 3.0.3

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.

What was the issue?  You really should try to make this work rather than
hack around it.
what we found was the decrementer is not generating an exception when it
becomes 0. and the timebase registers are not getting incremented too.
Does the decrementer actually tick until it reaches zero, or do it and
the timebase never tick?

Is the TBEN input to the CPU asserted?
