Created attachment 1224170 [details] screenshot of kernel panic Description of problem: Just upgraded from Fedora 24 with: dnf system-upgrade download --refresh --releasever=25 At reboot kernel-4.8.8-300.fc25.x86_64 shows immediately kernel panic. See attached screenshot. Hardware is a Lenovo T460S System Information Manufacturer: LENOVO Product Name: 20FAS2BM0E Version: ThinkPad T460s BIOS Information Vendor: LENOVO Version: N1CET48W (1.16 ) Release Date: 09/16/2016 Thankfully, fc24 kernel still work so I've been able to boot.
Same with kernel-4.8.10-300.fc25.x86_64
can you check you have an initramfs for that kernel and grub is loading it?

Still not working even with kernel-4.8.11-300.fc25.x86_64
Anything I can do to help debugging the issue?
Are you not using uefi on this system for some particular reason? Either way, 4.8.8-200.fc24 works but 4.8.8-300.fc25 does not? That would rule out a kernel issue, they are the same source. I am guessing dracut is missing something when creating the initrd. boot without the rhgb and quiet and see if you can get a better idea of the issue.

Confirmed, 4.8.8-200.fc24 works but 4.8.8-300.fc25 does not. Attaching lsinitrd output for the 2 images.

Found out that this is a duplicate of bug #1384469 ; removing dracut-fips and regenerating the initramfs solved the issue. *** This bug has been marked as a duplicate of bug 1384469 ***
