Subject: Oops on a converted ext4 system
Date: Tue, 26 May 2009 08:27:28 +0200 [thread overview]
Message-ID: <4A1B8BD0.6050203@wpkg.org> (raw)
I converted an ext4 filesystem with btrfs-convert, mounted it, and wanted to do "lzop -d ...".
The result was an immediate Oops (btrfs is on LVM, on dm-crypt, on /dev/sdb which is USB-connected).
mini-904.img.lzo dentry_open failed
BUG: unable to handle kernel paging request at ffffffcd
