Mythdora won't power down after shutdown
 

Hopefully somebody can help me with my problem, I've searched the forums but could not find a suitable solution.
I have a PCChips M830 version 5 motherboard with AMD Duron 666mhz cpu and 786mb DDR ram. I installed Mythdora 12.23 for playing videos on my tv and music on my stereo. Eventually I hope to get DSL out in the sticks where I live and can then stream movies from Netflix. I did not install MythTV. The installation went fine and I had no errors. I've done a lot getting it ready and it is stable. The problem I'm having is it will not power down. When I click "Shut Down" and then press F1 I can see the shutdown procdure and all looks fine until it gets to "Power Down", at which time it freezes and I have to flip the power switch on the power supply for it to power down. If I open a terminal and do "su root" and use "shutdown -h now" it exhibits the same behaviour. I've looked through the bios settings several times paying close attention to the "Power Management" section and have not seen anything relating to this. Doesn't seem like a big problem I know, but it keeps me from booting the machine from LAN since the ethernet card WOL settings are lost when powering down with the power supply switch. I would really appreciate the help if somebody knows what might be the cause.

does it saying when its shutting down? besides power down? -- like checking disks or something...

i would probably go to

/var/log/ and see what some of the log files are showing ....

cat whatever.log.file

and read through them seeing if you notice anything out of the ordinary...

Firstly, what is the point of installing MythDora if you don't install MythTV ? That is the whole point of the distribution. Otherwise you may as well install standard fedora.

Secondly, did a software shutdown ever work on this machine ?

Thirdly, MythDora have their own support forums which may be of more use.

Sorry for the tardy response but my email notifications stopped working. Yes I looked at the log files, particulary /var/log/messages. Nothing helpful there. Thanks for the reply.

I installed Mythdora in case I add a tv card later. I considered installing a standard Fedora version but I like the packages that come with Mythdora and wanted the option of installing MythTV later. Not sure what difference that makes with the problem I'm having though. Yes, it did at first power down normally. I can't think of anything I've done to affect that. As I said in my OP I've been through the bios settings and can't find anything in Power Management of help. I'm beginning to think it might be in the ATX power supply. I might substitute a differ PSU and see if that makes a difference. Thanks for the reply.

I have no experience with Mythdora but all distros do have a command line shutdown.
On Ubuntu 10.04 it's "sudo poweroff"
I sometimes have to resort to this after an update and after the system starts back up your shutdown button should work again.
So at a guess whatever command you use to get into superuser plus poweroff should work.
