Hello,

Once again, I would pretty much enjoy if you CC'ed the list on replies.

I meant, are you checking if 'newBun' is NULL _AFTER_ the kmalloc?

The kmalloc call will return NULL instead of a pointer to newly allocated memory whenever an error occurs. If by any chance you are not checking if 'newBun' is NULL after the kmalloc, then you should do it.

Also, if the panic happens _after_ the kmalloc, and not _during_ the kmalloc, I would say there's a slim chance of kmalloc being the cause of the panic.
