I don' t know yet. I was notified of the problem through bugzilla: http://bugzilla.kernel.org/show_bug.cgi?id=8128 The problem appears that a non-uptodate page has been marked dirty. I haven't found much in the way of changes between 2.6.20 and the current git tree to explain this. There's this one: http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=22c8ca78f20724676b6006232bf06cc3e9299539 I'm looking for for a caller to ->prepare_write() which marks the page dirty without calling ->commit_write(). Will, could you try reverting that patch? If that fails, narrowing the problem down with git-bisect would be helpful, if you have the time. Thanks, Shaggy -- David Kleikamp IBM Linux Technology Center
