sometimes, when booting up/resuming from disk, I get an oops[1].

obj_desc->common_field.access_bit_width is zero, but even after the
loop. Division before the loop is apparently OK.

Would please try below debug patch to see which region filed is
accessed?

Yes, except the fact, we wouldn't see anything :) -- I'll add inside the if a return statement or something to disallow the oops to flood screen.

Also, it doesn't happen regularly. Mostly several first tries after cold start. I hope this is a regression and not a HW problem, but it emerged after switching to 2.6.29-*, I will keep you informed.

Thanks.
