You're trying to take a mutex, while you already hold a spinlock, or
while you're inside an interrupt handler. In both of these contexts,
you're not allowed to sleep.

For more information, you can also read
http://lwn.net/images/pdf/LDD3/ch05.pdf.

But of course, posting your code, or at least, a link to it, would help.

Sincerly,

Thomas
