Hi, It happened again several times, this is the first message that appears in syslog related to ext4: EXT4-fs (dm-2): Inode 10910806 (ffff88006e445ae8): orphan list check failed! Here is the complete logfile http://preflight.aschendorff.de/tmp/syslog.1.gz How can we debug this further ? Should we kdump the kernel once this happens ?
