[linux-audio-user] CCRMA kernel minor Oops

Hello Fernendo,

I now have two machines running the same version of the CCRMA kernel
(2.6.14-0.10.rrt.rhfc4.ccrma). One is an old Pentium III and that runs
fine. The other is an AMD64 running in i386 mode and that gives me a
kernel Oops at boot. Strangely enough I am able to use the machine and
I only noticed this from looking at dmesg. I have attached the code to
the tail of this email.

Also, if I have a question about building a kernel module that is
having trouble with the preempt spinlock changes who should I talk to?
I emailed Ingo but haven't heard back for a few days.

Thanks for the kelp and the excelent packages!
