After the latest
dnf update, which included new
dracut (049-202.git20220511.0.1.el8_6) and UEK versions (5.4.17-2136.309.4.el8uek), all UEK kernels will not boot, resulting in a kernel panic caused by the inability to unpack initramfs:
Initfamfs unpacking failed: invalid magic at start of compressed archive
Rebuilding initramfs with different
dracut compression options doesn't seem to work (tried gzip, bzip2, xz, lz4, lzo, zstd)
Linux kernels seem to boot fine, so I'd think
dracut is not at issue, however UEK kernels that used to boot no longer do, which does seem to point back to
dracut although all it does is call an external compression command.
I prefer not to get mired in
dnf downgrade problems (previous version was I think 049-191.git20210920.0.2.el8). Any ideas how to get UEK kernel able to unpack the initramfs image files?
