Hi Tejun.
I am only reverting 8ee294cd9def0004887da7f44b80563493b0a097 though I first
revert part of 1d64b655dc083df5c5ac39945ccbbc6532903bf1 so it reverts
cleanly.
I am very sure of my test results; normally I get 4-5 bad resumes on a 20
hibernate loop and get no bad resumes with the commit reverted. I have
been very thorough in my testing to ensure I am not generating false
positives or false negatives (repeating the loops many times).
Below is the output you asked for (sysrq t).
Thanks.
~ Andy
