I spent some time this weekend investigating this issue more thoroughly.
In fact the regression caused by this commit has been corrected by
f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 (ACPI: Disable wake GPEs only
once.)
However, as I pointed out in the initial report, the MacMini doesn't
come out of suspend to ram because a commit in another merged patchset
broke it. I tracked it down to:
commit e9e2cdb412412326c4827fc78ba27f410d837e6e
parent 79bf2bb335b85db25d27421c798595a2fa2a0e82

[PATCH] clockevents: i386 drivers
This patch has already been mentioned in regression reports, but AFAICS
not related to suspend issues.
To be totally clear about what works and what doesn't:
79bf2bb335b85db25d27421c798595a2fa2a0e82
+ cherry-pick f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 ==> works
e9e2cdb412412326c4827fc78ba27f410d837e6e
+ cherry-pick f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 ==> broken
To try to get more information, I commented the call to
do_suspend_lowlevel in drivers/acpi/sleep/main.c and used
CONFIG_DISABLE_CONSOLE_SUSPEND. Interestingly, the suspend/resume cycle
completes correctly in this mode.
