Hmm... I am very very surprised that that commit could have such consequences.
Are you sure that it is it?
As to the debugging I really don't know what to look for.
Could you please describe your CPU?
Perhaps use procstat -kk -a | fgrep -i acpi to check if there are any threads
stuck somewhere in acpi after a resume.
Maybe also compare output of sysctl hw.acpi and dev.cpu before and after a
resume, with and without r244616.
