I did some more testing and although it seems several devices cause suspend/resume problems, the biggest issue is with bluetooth and usb. I went to the bios settings and disabled all the integrated devices. In that configuration I did 10 suspend/resume cycles without problem. Then I started enabling a few devices. With WLAN enabled I had one lock-up out of 10 suspend/resume cycles, but it was a lockup during suspend, not during resume, so it is probably another issue. However enabling bluetooth makes it impossible to suspend/resume more than once or twice (after the second resume, the machine powers off during resume). But the strangest thing is this: disabling bluetooth but enabling outside USB ports systematically triggers the unexpected power off during boot, the system becomes unbootable.
