Ooops in kmalloc from request_region

[Liam Davies <ldavies@agile.tv>]

I am currently at the stage of calling request_region in my irq_setup 
function.
The call to request_region does a kmalloc which oops. The box has 256Mb Ram.

Is this the right stage to be doing this call? Is there something that I 
have missed
in setting up the memory regions or paging?


Thanks
Liam Davies
