Sep 25 00:13:20 quincunx kernel: [ 5942.889728] PM: Finishing wakeup.
I'm not sure whether this would be responsible for a crash though, and
there isn't any evidence of the crash after this point. Looking at the
kernel source for that warning, there is the following comment:
/* Warning on suspend means the RTC alarm period needs to be
* larger -- the system was sooo slooowwww to suspend that the
* alarm (should have) fired before the system went to sleep!
*
* Warning on either suspend or resume also means the system
* has some performance issues. The stack dump of a WARN_ON
* is more likely to get the right attention than a printk...
