Are there any messages on the screen or in the logs when the system powers down? Related? #238523
No, no messages at all on the screen. And I guess nothing written to logfile, because it's still in initrd phase? And if not, syslogd/klogd is not started at that moment. It's just before rhgb would show...
Is there a way to debug this? I tried booting with acpi=off apic=no but it doesn't help. Maybe with a serial console? Or enabling udev debug info? Maybe it's more obvious when one would look at the changes between the FC6 release kernel and the first FC6 errata kernel?
Somehow, this seems to be fixed after the last few kernel updates. I didn't really notice anything that could have fixed it, but whatever... If I encounter it again, I'll report back here.
