Hello all,
I am getting kernel BUG when i deal with big files :-
kernel BUG at page_alloc.c:203!
I am using 2.4.1 on SH4 and using only 32 MB RAM
without hard-disk, so only thing i am using is 32 MB
RAM .
/* page_alloc.c */
if (BAD_RANGE(zone,page))
BUG();
DEBUG_ADD_PAGE <--- line no 203
/* linux/swap.h */
#define DEBUG_ADD_PAGE \
if (PageActive(page) || PageInactiveDirty(page) || \
PageInactiveClean(page)) BUG();
Can someone please guide me and let me know the
work-around for this kernel BUG.
Thanks for your help.

I also want to use latest kernel but new kernels give
many compilation errors and their links are broken for
SH platform.
Thanks.

I have noticed that difference in 2.4.1 and 2.5.25 is
:-
(2.4.1)
if (BAD_RANGE(zone,page))
BUG();
DEBUG_ADD_PAGE
(2.2.25)
if (bad_range(zone, page))
BUG();
prep_new_page(page);
prep_new_page(page) is replaced with DEBUG_ADD_PAGE
and prep_newpage is :-
/*
* This page is about to be returned from the page
allocator
*/
static inline void prep_new_page(struct page *page)
{
BUG_ON(page->mapping);
BUG_ON(PagePrivate(page));
BUG_ON(PageLocked(page));
BUG_ON(PageLRU(page));
BUG_ON(PageActive(page));
BUG_ON(PageDirty(page));
BUG_ON(PageWriteback(page));
page->flags &= ~(1 << PG_uptodate | 1 <<
PG_error |
1 << PG_referenced | 1 <<
PG_arch_1 |
1 << PG_checked);
set_page_count(page, 1);
}
vs
#define DEBUG_ADD_PAGE \
if (PageActive(page) || PageInactiveDirty(page) || \
PageInactiveClean(page)) BUG();
Can i also replace DEBUG_ADD_PAGE with prep_new_page
in 2.4.1. Is it OK ?
Thank you very much for your help.

I reckon you'll have to get in touch with the SH port maintainers
and ask them directly. Have a peek in $linuxsrc/MAINTAINERS.
Have you tried any of the kernels available from
http://www.m17n.org/linux-sh/
?
