Bug ID: 1851216 Summary: kmod abort installing rawhide kernel Product: Fedora Version: 32 Status: NEW Component: kmod Assignee: kmod-maint@lists.fedoraproject.org Reporter: gtwilliams@gmail.com QA Contact: extras-qa@fedoraproject.org CC: jonathan@jonmasters.org, kmod-maint@lists.fedoraproject.org, skozina@redhat.com, ykaliuta@redhat.com Target Milestone: --- Classification: Fedora

Description of problem:

I am trying to install the rawhide kernel to test another problem that I want to report, but the install ends up looping with bash calling weak-modules --add-kernel over and over consuming a CPU and never finishing the kernel install.

The abrt servers are down, so I copied this out of /var:

Log of console dnf command. I had to find the process pid that was spawning depmod constantly (bash) and kill it with -kill to stop the processing:
