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.

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 > Does 3.4.y from experimental exhibit the same problem? 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. > Please attach full "dmesg" output from booting and reproducing the bug. 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.

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 [1] http://www.asrock.com/mb/download.asp?Model=E350M1&o=BIOS
