Comment 2 for bug 2060780

Same problems here. Get error messages like "Too many symlinks" and exactly the same as in this description.
Found also, that CIFS mounts to Netapp mostly works, but df -h doesnt show them and mounts to other CIFS shares doesnt work.
Verified it on 5 Linux Boxes, all started failing after patch and working again when go back to snapshot from yesterday (before kernel patch): These patches are he "bad ones":
