Print for tracing bugs

Print for tracing bugs

[Alan Horstmann]

I am trying to trace problems with SPDIF in ice1712.c.  Is there an easy way 
to print messages/values out in a terminal window from the running sound 
driver (using a version of print added in the code), perhaps after doing  
'rcalsasound restart' from a Konsole?

Yes just add printk()'s to the driver code.

No idea, that's a KDE issue.  Most GUI terminals don't print out the
kernel messages.

Try a text console.

Thanks.  I can get these to print to var/log/messsages, but how do I get them 
to come immediately to a konsole?

In the konsole type
tail -f /var/log/messages

As messages appear in the file, they will be displayed.
