Re: Ubuntu 22.04 LTS system freezes 5 minutes then unlocks on nouveau, was stable on 20.04 w/nvidia

Hello,

Upgrading from Ubuntu 20.04 LTS to Ubuntu 22.04 LTS you upgraded the
kernel from version 5.4 to 5.17.

A similar issue ("[GT216][Linux 5.16.4] Long stalls in
dma_fence_default_wait") has been reported here for the Nvidia GT216:
see here [1] for the report and for the workaround and kernel patch.

HTH
