Description of problem: Right at the beginning of the boot there is a kernel panic (with 4.9.x kernels). Version-Release number of selected component (if applicable): - kernel-4.9.4-201.fc25.x86_64 - kernel-4.9.5-200.fc25.x86_64 - not affected: kernel-4.8.16-300.fc25.x86_64 How reproducible: Always Steps to Reproduce: 1. Reboot System 2. Boot one of the named kernels above Actual results: Kernel Panic Expected results: There shouldn't be a kernel panic. Additional info: will add info soon... My setup: - Acer Aspire V3 771G - Intel(R) Core(TM) i5-3210M CPU - EFI - Grub2 - /boot/ is located on subvilume root in btrfs in luks encrypted volume
I also use dracut-044-78.fc25.x86_64. Update: After running re generating the initramfs (`dracut -f`) this also happens with kernel-4.8.16-300.fc25.x86_64. So it looks to be a dracut problem...

This is a dracut issue, not an actual kernel issue. Do you have dracut-fips installed? If so, please remove and rebuild your initramfs
Thanks Laura for your response and pointing me in the right direction. Uninstalling dracut-fips solved the problem. So did I understand it correctly that I need hardware entropy generators for FIPS? So this isn't a bug at all because I think there is no such thing in my pc (accessing /dev/hwrng says "No such device" and there is no tpm)... Is dracut-fips included in a standard installation or did I install it recently? :D
