While I haven't been able to figure out a proper explanation for what's going on, I do have a workaround that seem to work reliably and allows those machine to sleep and wakeup properly again. I'll re-update that code if/when I ever find exactly what is happening with those CPU revisions. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Linus Torvalds --- Reading git-diff-tree failed
