We use a similar technique to ppc32: We set a thread local flag
to indicate that we are about to enter or have entered the stop
state, and have fixup code in the async interrupt entry code that
reacts to this flag to make us return to a different location
(sets NIP to LINK in our case).

Hi:

problem when doing raid5 recovering.

Thanks for the information. Sorry that we missed the patch. It was not done

This is a proof of concept at the moment, but if the corner cases
can be sorted out, then this might be the best way to replace
the defconfig functionality. This patch implements Linus' idea

Sorry if these aren't right place, please point me to the right
direction if you can :)
When trying new 2.6.35-rc4, our kernel team (ArchLinuxPPC) has tried

We have removed radeonfb, and all others framebuffer driver, and added

This uses Uwe's script (modified by Olof Johansson to speed it up

them before and after this patch and comparing the results.
