Created attachment 1782009 [details]
AVC denial messages from /var/log/audit/audit.log

Description of problem:

Upgrade procedure from Fedora 33 to F34 apparently did not complete. OS is now Fedora 34, but attempt to install updates on a later reboot did not complete. "Updates available" showed Updates to install 381.9MB. Reached about 60% of the way through install process, then prompted for re-start. On attempting to reboot, cycle gets repeated, seemingly indefinitely.

Version-Release number of selected component (if applicable):

Not known


How reproducible:

At least 6 times

Steps to Reproduce:
1. Boot Fedora, after upgrade
2. Accept all "updates available" (381.9MB, for 213 packages)
3. Reboot when prompted


Actual results:

Gets into loop.

AVC denial messages in /var/log/audit/audit.log, similar to

type=AVC msg=audit(1620736925.105:3034): avc:  denied  { integrity } for  pid=2621 comm="pmdakvm" lockdown_reason="debugfs access" scontext=system_u:system_r:pcp_pmcd_t:s0 tcontext=system_u:system_r:pcp_pmcd_t:s0 tclass=lockdown permissive=0


Expected results:

No AVC denials, install process completes

Additional info:

KDE spin of Fedora 34, SELinux in targeted mode, NVidia graphics driver (not Nouveau).
