Looks like a corrupted file system, we expect inode 1109312 on /usr
to be unallocated but reading it from disk results in an inode with
mode 0x2f20 (chr, sticky, suid, sgid, mode rr-), looks like garbage.

I suppose fsck will not complain about unallocated garbage inodes.

Is the /usr file system UFS1 or UFS2, output of dumpfs could help.
