Kirk,

Thanks, I'll take a look at the web stuff in a few days.  In the 
meantime I've now got some more to go on with finding the reason for the 
crash on the Raspberry Pi...

Yesterday I got a serial console cable through the post.  I connected it 
to the UART on a Raspberry Pi and for the first time have been able to 
trap the 'kernel oops' that occurs when SpeakUp crashes.

I get an 'unable to handle kernel NULL pointer dereference at' error.

Next I just need to learn how to use kdb, kgdb, gdb or a combination of 
all three to debug where this crash is occurring. As yet I don't know 
how to be able to trace back through the source to find the error.  I 
could just put a bunch of 'printk' calls in the source I guess but I am 
not sure if that will slow things down too much.

I am following the forwarded messages from the kernel guys with 
interest.  It is good to see that there still efforts to push things 
forward.  I'd also be happy to do some of the clean-up tasks.  I've 
written tons of Perl in my time and it strikes me that changing some of 
the variable names and stuff could be automated.

Mike
