Subject: exit_mmap() BUG_ON triggering since 3.1
Date: Wed, 15 Feb 2012 13:33:18 -0500 [thread overview]
Message-ID: <20120215183317.GA26977@redhat.com> (raw)
We've had three reports against the Fedora kernel recently where
a process exits, and we're tripping up the
BUG_ON(mm->nr_ptes > (FIRST_USER_ADDRESS+PMD_SIZE-1)>>PMD_SHIFT);
in exit_mmap()
It started happening with 3.1, but still occurs on 3.2
(no 3.3rc reports yet, but it's not getting much testing).
https://bugzilla.redhat.com/show_bug.cgi?id=786632
https://bugzilla.redhat.com/show_bug.cgi?id=787527
https://bugzilla.redhat.com/show_bug.cgi?id=790546
I don't see anything special in common between the loaded modules.
anyone?
Dave
