Title:
linux-image-5.4.0-97.110 freezes by accessing cifs shares
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ubuntu 20.04 with kernel image 5.4.0-97.110 randomly freezes when we
access cifs shares. The system needs a hard reset after the freeze.
The previous kernel image (5.4.0-96.109) does not show this behavior.
Multiple Ubuntu 20.04 systems running on kernel image 9.4.0-97.110 are
affected on our sites.
The cifs shares are accessed via autofs using Kerberos authentication.
The following info is the only error message we could actively catch
on a different system before the system was frozen:
