Dear Jonathan,
first let me thank you for your great – first wanted to write
»tremendous« but `ding` showed it also means terrible, so I changed it –
work on Debian (especially the Linux kernel) and helping users like me.

That statement was wrong. See below.

First I need to add more information regarding this report.
Shut down also does not work sometimes, that means, it writes `Power
down` to the monitor but the fans keep running. Testing this further
with
$ echo mem | sudo tee /sys/power/state
and
$ sudo pm-suspend
I could reproduce this bug also with `pm-suspend` and sometimes it also
worked with writing `mem` to `/sys/power/state`.
To summarize, suspend to RAM and shut down *arbitrarily* have this
problem and I did not find a way yet to

I did not have time yet to test 3.4.y since I am using fglrx now and I
do not know if fglrx will work with 3.4.y.

To get further debugging information I set up netconsole by loading the
module with `modprobe` and doing `dmesg -n debug`. Furthermore I removed
`quiet` from the Linux commandline and added `debug` and
`no_console_suspend`.
Since adding `no_console_suspend` suspending to RAM worked as expected,
that means the power supply/fans were turned off.
The output (same between both methods) is the following.

*But* waking up does not work. :/ I cannot SSH into the system and
netconsole does not send anything either although fans are on and the
LEDs at the Ethernet jack light up too.
Furthermore I found out that there is a BIOS upgrade [1], where the
changelog is the following.
Fix Ubuntu 11.04 can not shut down issue.
So I will do some further testing – I guess the easiest is the BIOS
upgrade – and report back.
Thanks,
Paul
