The problem presents itself coming out of hibernate as well as on initial boot.  However, when you then login or restart pnmixer from the command line it loads and works fine the whole time you remain logged in, don't hibernate, and don't reboot.

Thanks! Actually, it is one better, but for the syslogd message, I have resumed from hibernate for five times since last morning. Not sure when my luck will run out:-)

OK, I will try this, thanks! Sorry, may I ask: what is the difference between these two?

Yes, that is what I have set it up now as, for when I next crash.

Yes, I think you (or someone else) suggested this earlier but I am not waiting for not resuming for hibernate.

OK, thanks! Hopefully, the workaround will be fine.

Yes, that is a possibility. I will try this too.

Btw, there are more crash messages of something in my dmesg now:

$ dmesg | fpaste
Uploading (182.4KiB)...
http://ur1.ca/iff0k -> http://paste.fedoraproject.org/143313/41372784

Not sure if this means much: of course, in the past, I have not looked at dmesg so frequently (or pretty much at all) so I am not sure that such messages are a common occurrence in general.


Thanks again!
Ranjan
