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.

[Kernel-packages] [Bug 1959665] Re: linux-image-5.4.0-97.110 freezes by accessing cifs shares
Hi, thanks for the quick reply. I can confirm, that while running on 5.4.0-98-generic #111~lp1959665.1 I was able to access all of our cifs shares without issues. A script, which creates, reads, modifies and deletes files on different cifs shares also works without any issue. Removing the latest cifs patches from kernel 5.4.0-97.110 seems to fix our issue. I will keep testing on 5.4.0-98-generic #111~lp1959665.1.

Hello, Thanks for the help! :) Are these cifs patches present in 5.13.0.27? I got similar issues with 5.4.0.97 and 5.13.0.27, and moving to previous releases fixed the issues in both cases! :) Cheers!

Hi, thanks for the fast reply! I have just installed it: :~$ uname -a Linux foo.bar 5.4.0-98-generic #111~lp1959665.1 SMP Tue Feb 1 19:50:04 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux I mount all shares and start my tests (ncdu and a simple bash testscript). With 97#110 it takes 30 seconds to crash a machine. ...with the 98#111 the scripts work (i abort the test after 60 minutes). I dont get a kernel panic with this kernel.

[Kernel-packages] [Bug 1959665] Re: linux-image-5.4.0-97.110 freezes by accessing cifs shares
** Summary changed: - linux-image-9.4.0-97.110 freezes by accessing cifs shares + linux-image-5.4.0-97.110 freezes by accessing cifs shares ** Description changed: - Ubuntu 20.04 with kernel image 9.4.0-97.110 randomly freezes when we + 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: [#3] SMP PTI CPU: 0 PID: 21294 Comm: automount Tainted: G DOE 5.4.0-97-generic #110-Ubuntu Hardware name: Dell Inc.
