Package: linux-2.6
Version: 2.6.32-45
Severity: normal
Kernel bug observed in syslog when performing an rsync operation. I use rsnapshot and I believe an rsnapshot operation "conflicted" or "interfered" somehow with my manual rsync command. The source and destination are USB HDDs with ext4 filesystems. After the kernel bug was observed I discovered the source filesystem had a corrupt filesystem. If it is relevant I was using the rsync command with --hard-links and I also observed messages of this sort: "[1075483.039915] EXT4-fs error (device sdb1): htree_dirblock_to_tree: bad entry in directory #7143723: directory entry across blocks - block=34323866offset=0(0), inode=135151872, rec_len=66180, name_len=66" and "Jul 1 06:33:06 altair kernel: [1075335.376996] EXT4-fs error (device sdb1): ext4_lookup: deleted inode referenced: 8954048".
Relevant kernel log trace with bug:
