bugcheck! message at shutdown

[Masao Fukuchi]

Hi all,

I got bugcheck! message when I shutdown my Tiger4.
I noticed this error after I updated the kernel to 2.6.5.
Alex posted same kind of mail before.
http://marc.theaimsgroup.com/?l=linux-kernel&m=108127270905214&w=2

So, I sent him mail.
But he doesn't know the proper fix(he just removed __init
from the declaration of get_boot_pages to get rid of bugcheck!).

If you have any information, please let me know.

Thanks,
Masao Fukuchi

Hi Masao,

   You can remove the __init from the declaration of get_boot_pages, but
I'm not sure that's the proper fix.  It gets rid of the bugcheck for me
though.  Please post to linux-kernel as well, perhaps it will get
someone's attention who knows how to fix it properly.  I'd assume we
really only want to call get_boot_pages on bootup, and the
system_running flag is being used improperly.  Thanks,

	Alex
