I have written a driver (for the CD Rom on the Sega Dreamcast). I have

Other developers tell me I should mark them as __devinit.

I think otherwise it has dealt with most people's suggestions. The one
exception is that Jens suggested using sector_div, though I found that

I see that other drivers use memcpy - and will happily convert
bus
problems.
Following requests the bus driver now has a mutex to guard against a
rogue process adding to the waitq.

OK, why does this line occasionally return true:
if ((maple_dev-interval 0) (jiffies maple_dev-when))
while this one never does (no other changes made):
if ((maple_dev-interval 0) (time_after(jiffies, maple_dev-when)))
Is this a gcc issue or what?

You need to explain what you mean (at least to me!).
If you mean will it degrade gracefully - not without this patch if set

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
