Comment 1 Bruce Allan 2009-08-04 18:36:32 UTC 
We (Intel LAD) believe we have the appropriate fix for this that will also address the original issue the previous patch was meant to fix.  The latest patch is in our internal validation at the moment and should be pushed upstream once it has passed our testing.
Comment 2 Bruce Allan 2009-08-19 23:27:53 UTC 
Should be fixed by commit 148675a7 in 2.6.31-rc5
Comment 3 Rafael J. Wysocki 2009-08-19 23:29:02 UTC 
OK, closing.
