Not here unfortunately. Suspend still fails with itpm=1, and I get this
in my logs

Nov 29 15:52:32 doris kernel: [  649.110527] resource map sanity check

Also, this patch:
http://marc.info/?l=linux-kernel&m=128769741101534&w=2

Looks for a string that is absent from my Vaio SZ650, so the workaround
is not applied (and if it was, it probably wouldn't work, right?).

I posted my DSDT to bugzilla:
https://bugzilla.kernel.org/attachment.cgi?id=38072
