BUG at rmap.c:212
Hello,
yesterday I told (in IDE thread) that BUG at rmap.c:212 is probably
already fixed by changeset 520. Unfortunately, it is not, I got it again with BK tree. It happened again when 'ntpd' called exit() upon receiving sigterm.
Stack trace:
page_remove_rmap
zap_pte_range
zap_pmd_range
unmap_page_range
exit_mmap
mmput
do_exit
sys_exit
syscall_call
If it is not known bug, I'll rebuild kernel with DEBUG_RMAP. Unfortunately it looks like that machine must have uptime > 12hrs to trigger this. Probably updatedb or some other task must be run to try to swap ntpd out?
Best regards,

Line 212 is 'pte_chain_unlock(page);' right ?
What configuration are you running ? SMP ? PREEMPT ? What compiler ?

It is not a known bug. In fact I've never seen this one before.
kind regards,
