Okay, will do. > Were there other interesting messages before or after the above? No, nothing at all. The bogus i_mode message has showed up a few more times today though: Mar 10 10:42:41 hermes kernel: init_special_inode: bogus i_mode (53253) Mar 10 11:29:34 hermes kernel: init_special_inode: bogus i_mode (53253) Mar 10 12:41:39 hermes kernel: init_special_inode: bogus i_mode (53253) > If you try a manual getfacl of the above files do you still get the error? Yeah, same thing: hermes:/srv/samba/local# getfacl apps/Gestalt.Net/SetupCD/program\ files/Business\ Objects/Common/3.5/bin/Cdo32sv.dll getfacl: apps/Gestalt.Net/SetupCD/program\040files/Business\040Objects/Common/3.5/bin/Cdo32sv.dll: Input/output error Nothing extra showing up in dmesg after doing that, so it's possible the two are unrelated - although, the coincidence would surprise me.
