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 ====================== kernel: [ 345.226523] SysRq : Show State kernel: [ 345.226531] task PC stack pid father kernel: [ 345.226535] init S f4a47b68 5488 1 0 0x00000000 kernel: [
