Date: Fri, 9 Jan 2009 16:36:45 -0800 From: "Pallipadi, Venkatesh" <venkatesh.pallipadi@...el.com> To: linux-kernel <linux-kernel@...r.kernel.org> Cc: tytso@....edu Subject: kernel BUG at fs/ext/super.c:428 I started seeing this BUG on one of my test systems during file system unmount on the way to shutdown/reboot. The problem is present with latest git and not present in 2.6.28. Hoping that someone has already seen this and fix available before I go git bisect way... Let me know if you need any more detais about the bug or test system.
