Bug#973613: cifs-utils: CIFS kernel module crash
Hi, I cannot replicate the issue with my currently-installed kernel "5.10.0-3-amd64 #1 SMP Debian 5.10.13-1 (2021-02-06) x86_64 GNU/Linux". Kind regards. Dr. Koutheir Attouchi.

Bug#973613: Soft lockup
Running the same command again causes a lock down and the message: kernel:[ 932.068256] watchdog: BUG: soft lockup - CPU#3 stuck for 23s! [mount.cifs:3945] And the only way to reboot is to force a shutdown.

Bug#970420: python: Unmet dependencies when installing python package
If the package is gone, but it was the only manually installed package to get Python, then the whole Python distribution becomes auto-removable, unless people manually mark the python2 and/or python3 as manually installed. Many people will just find out that they don't have python support anymore, even though they installed python manually in the past. There should have been some change log to notify people about this change and the needed manual intervention.
