What is the server type? I want to be able to rule out freeing the directory cache on umount. Do you know if it is reproducible on current mainline (6.11-rc1)

> Do you know if it is reproducible on current mainline (6.11-rc1) I may try that one 0.rc0.20240720gt3c3ff7be.307.vanilla.fc40 later this week https://copr.fedorainfracloud.org/coprs/g/kernel-vanilla/mainline/
(In reply to Steve French from comment #1) > What is the server type? I want to be able to rule out freeing the directory > cache on umount. Do you know if it is reproducible on current mainline > (6.11-rc1) Tried two kernels Here are the steps performed: - Established the VPN connection - Mounted the DFS share - Listing of the directories under the share works fine. - Disconnected from VPN: shutdown the VPN client - Connected the VPN once again. - Listing of the directories under the share does not works any more. The CIFS kernel layer tries to restore the connection in vain continuously. 1) 6.11.0-0.rc1.20240731gte4fc196f.317.vanilla.fc40.x86_64 2) 6.11.0-0.rc1.20240802gtc0ecd638.319.vanilla.fc40.x86_64; The kernels behaves in the same way. No kernel crashes observed, but the whole network stack is broken. I am not able to restart any systemd service. Even reboot ends up with a timeout.

Closing the bug report since I am not able to reproduce it reliably any more.
