Sorry - you're right about that, because i did: git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git v4l-dvb cd v4l-dvb git remote add linuxtv git://linuxtv.org/media_tree.git git remote update git checkout -b media-master remotes/linuxtv/staging/for_v2.6.38 ... so it is not "pure" Linus's git tree I'm sorry about misleading. > However, looking at the BUG_ON which you reported: > >> Nov 12 23:19:34 draco kernel: [ 997.220452] kernel BUG at fs/ext4/page-io.c:146! > > I'm pretty sure it's a bug which is fixed as of v2.6.37-rc1-git6, > specifically by commit id: f7ad6d2e9 (ext4: handle writeback of inodes > which are being freed). > > Best regards, > > - Ted good to know, that it is fixed now :) Thank you regards, -- Mariusz Bialonczyk jabber/e-mail: manio@skyboo.net http://manio.skyboo.net
