This bug is awaiting verification that the linux-azure/5.4.0-1069.72 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you! ** Tags added: verification-needed-focal -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1959665 Title: linux-image-5.4.0-97.110 freezes by accessing cifs shares Status in linux package in Ubuntu: Invalid Status in linux source package in Focal: Fix Released 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: general protection fault: 0000 [#3] SMP PTI CPU: 0 PID: 21294 Comm: automount Tainted: G D OE 5.4.0-97-generic #110-Ubuntu Hardware name: Dell Inc.
