[Bug 43961] Re: Power down after shutdown does not work...

[bierce]

My problems with this initially seemed to have gone away when I added
"acpi=force lapic" to the boot line.  But I have since had failed
powerdowns; it improved the behaviour of the machine, but it was not a
complete fix, unfortunately.  They say that a mule will work
faithfully for you for 20 years just to get a chance to kick you once.
 Another year of this, and it will be time to consider a change in the
Linux masot.  :)

I am now trying to discover whether the freeze happens at a consistent
point in the shutdown process.  Removing LVM did not seem to help, so
I will be restoring that.  In the final /etc/init.d/halt script, I
have removed the -i and -h options (down network and down disks) from
the halt command, and added a bunch of sleep/retries.  If the problem
persists, I will try using plain "init 0" to shut down, and see if
that's related.

This is a real bugger, this bug.
