Tried to patch 2.6.35-rc5 but I get:

/usr/src/my2.6> sudo patch -p1 < patch_yinghai
patching file mm/page_alloc.c
Hunk #1 FAILED at 3634.
1 out of 1 hunk FAILED -- saving rejects to file mm/page_alloc.c.rej
patching file mm/bootmem.c
Hunk #1 FAILED at 833.
Hunk #2 FAILED at 986.
2 out of 2 hunks FAILED -- saving rejects to file mm/bootmem.c.rej

Any hints?

It seems that 2.6.35-rc1 does not have the CPU eater problem. I still
running it without any interference (though I was away from the
computer for some time).

Best
Zeno
