Attaching dmesg output after a fresh reboot.
Attaching /var/log/messages after the machine rebooted after going to S3.
Attaching a netconsole log of the machine during suspend.

I'm sorry to say that I cannot see any reasonably useful information in
these, though. The machine is a laptop, so no serial console available.
