After a shutdown or suspend, the machine appears to completely shutdown (all fans stop and are quiet), after a few seconds, everything is powered up again by itself.
Despite the many offered solutions here in the forum, my pc keeps on rebooting after shutdown and after suspend.
IMPORTANT UPDATE: it appears that the pc shuts down without restart when ZFS is performing a scrub. I assume this means that something is going wrong when the pc is shutting down with regards to ZFS (unmount? unshare ?). Any clues ?
- I tried adding
acpi=noirq
to the grub file, after that I executedupdate-grub
. - I tried adding
acpi=no apm=no
instead, but that caused suspend to not terminate properly and result in a reboot. Shutdown causes reboot like before. - Tried
sudo halt
,sudo shutdown -h now
- Tried installing
laptop-mode-tools
in Ubuntu 12.10 - De-activated WOL
- I even tried to change "auto" to "on" in the "control" files for every device.
- Upgraded to Ubuntu 13.04 (I believe
laptop-mode-tools
are not available under 13.04?) - Tried messing in the BIOS ACPI settings (switched everything off, with no result)
None of it seems to work, and I'm getting out of info on the forum...
Questions:
- Is there anybody that has an idea what could go wrong ?
- Could ZFS be the cause ?
- Or the fact that I have an additional pci-e network adapter ? (some WOL issue)
- I'm not too familiar with Ubuntu, how can I access/dump the logtext when the system is going to shutdown or suspend (not the arrow key, but a file) ?
Running Ubuntu 13.04 now, with ZFS (6 disks) as a NAS on a ASRock B75 Pro3-M, Intel Pentium G2020, 16 Gb RAM, additional pci-e network adapter.
