I should have said, of course, that it was -rc6 and earlier that would not boot without Jiang Liu's patches. I applied those patches to rc-6 and my resume after suspend to disk problem was fixed. For a subsequent week I have been running with the patches applied to -rc7, with Andrew's patch also applied for the last 3 days. -rc7 was not subject to the resume problem because the patch which broke it had been reverted. All this has been on a 64bit laptop, but running a 32bit kernel with HIGHMEM.
Apologies for yesterday's inaccuracy. I shouldn't send testing reports when I'm in a hurry.
