Subject: kernel BUG at arch/x86_64/mm/../../i386/mm/hugetlbpage.c:140!
G'day
I'm hit a bug on 2.6.21-rc1 at startup of mysql with 'large-pages' flag set.
(at this point mysql trying to allocate pages from hugetlb pool by sysv
shm syscalls). Seems like it could be triggered by previous badness
and probably hugetlb itself is not related. Anyway i couldn't reproduce
it by now with 2.6.21-rc2 git commit 562aa1d4c6a874373f9a48ac184f662fbbb06a04.
Very likely it has been fixed somwhere between 2.6.21-rc1 and -rc2,
but i couldn't find something related by git log so any comments are welcome.
