Scott,
The patch "Convert some mftb/mftbu into mfspr"
(beb2dc0a7a84be003ce54e98b95d65cc66e6e536
<https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/powerpc/include/asm/reg.h?id=beb2dc0a7a84be003ce54e98b95d65cc66e6e536>)
breaks startup on MPC885.
The CPU traps (SoftwareEmulation trap) at sched_clock() when trying to
read TBU with mfspr.
Reverting the patch solves the issue.
What's the prefered way to fix this ?
Christophe
