I ma having problems with the pvr2 fb on the Dreamcast in 2.6.22-git17
- when the code is executed it appears to lock the Dreamcast up.

The problem seems to be:

 fb_notifier_call_chain(FB_EVENT_FB_REGISTERED, &event);

In drivers/video/fbmem.c

This hasn't been an issue before, so are there any recent changes that
might have caused this?

(fb_notifier_call_chain calls a succession of stubs ending in
__blocking_notifier_call_chain in kernel/sys.c)


Looking further, the problem can be further narrowed to

ret = nb->notifier_call(nb, val, v);


in

static int __kprobes notifier_call_chain(struct notifier_block **nl,
					unsigned long val, void *v,
					int nr_to_call,	int *nr_calls)

In kernel/sys.c
