Hi Takashi,
If I have some process with the sound device opened in my eeepc (say KDE's kmix) and try to power off the machine, for example with:
# echo o > /proc/sysrq-trigger
The machine will not power off.
At which point does it stop? What shows alt-sysrq-t (or w) output?
But it does work if I remove the snd-hda-intel module before issuing the echo above.
This problem seems to be pretty popular among distros, I could find it reported for Mandriva, Ubuntu and Fedora.
Hmm, I haven't heard of unfixed issues.
Its workaround is also documented in a few wikis: people are doing a 'rmmod snd-hda-intel' in the last halt stage (ie, halt script in etc).
I hate wiki or forum just recommending a wrong workaround :)
thanks,
Takashi
