For the Cockpit storage page we have a test which creates 200 scsi disks to catch issues with kernel <-> udev <-> udisks. Upgrading to 1:2.8.5-0.rc3.fc43 causes the disks to sequentially load and take a lot longer then our normal making the test fail. Its hard for me to produce an exact reproducer but my suspicion is that the new `nfsrahead` process is causing udisks to receive udev events a lot later then normal. Reproducible: Always Steps to Reproduce: 1. modprobe scsi_debug num_tgts=200 2. notice a nfsrahead process spawned per disk? 3. Additional Information: nfsrahead is spawned from udev [root@fedora-43-127-0-0-2-2201 ~]# pstree -sap 2897 systemd,1 --switched-root --system --deserialize=54 └─systemd-udevd,648 └─(udev-worker),2421 └─nfsrahead,2897 70:64 And tons of nfsrahead processes are spawned [root@fedora-43-127-0-0-2-2201 ~]# ps aux | grep nfs root 2466 0.0 0.2 4040 2568 ?

Here is a scratch build [1] Could somebody test this since we (upstream and I) were not able to reproduce the problem tia [1] https://koji.fedoraproject.org/koji/taskinfo?taskID=143290490
I suspect to reproduce it you just need to create a scsi_debug device ie. modprobe scsi_debug num_tgts=1, as I package for Arch Linux I tested the two proposed patches on the mailing list and they seem to resolve the coredump, and I also suspect the performance regression: https://gitlab.archlinux.org/archlinux/packaging/packages/nfs-utils/-/merge_requests/2/diffs I've also tested the scratch build and can confirm our scaling test which creates 200 scsi disks passes now and I don't see coredumps anymore.
