This board is using kernel 2.6.21.1 with balloon mods (http://balloonboard.org/cgi-bin/viewcvs.cgi/balloon/trunk/kernel/ ) with what appears to be a yaffs around this vintage: "$Id: yaffs_fs.c,v 1.59 2007/03/20 20:59:40 charles Exp $" "$Id: yaffs_guts.c,v 1.48 2007/03/12 20:55:39 charles Exp $"; (see http://balloonboard.org/cgi-bin/viewcvs.cgi/balloon/trunk/kernel/2.6.21.yaffs.patch?rev=163&view=log ) It has a 1GB yaffs partition and after a couple of weeks use (generally just being turned off, not unmounted) seems to have got itself in a state where the checkpointing code oopses the kernel (see log below). I should have this on my desk shortly. Anyone got any suggestions what might have gone wrong, as it would be good to avoid this, and I want to give it an analyse? ----- Forwarded message from His Majesty ----- From: His Majesty Date: Mon, 30 Jul 2007 12:38:25 +0100 To: Wookey Subject: Achtung...
