kernel bug(VM_BUG_ON_PAGE) with 3.18.13 in mm/migrate.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I got below kernel bug error in our 3.18.13 stable kernel.
"kernel BUG at mm/migrate.c:1661!"

Source code:

1657    static int numamigrate_isolate_page(pg_data_t *pgdat, struct page *page)
1658   {
1659            int page_lru;
1660
1661           VM_BUG_ON_PAGE(compound_order(page) &&
!PageTransHuge(page), page);

It's easy to trigger the error by run tcpdump in our system.(not sure
it will easily be reproduced in another system)
"sudo tcpdump -i bond0.100 'tcp port 4242' -c 100000000000 -w 4242.pcap"

Any comments for this bug would be great appreciated. thanks.
