I simply tried something that seemed would obviate BRS, but disabling cores is
a performance killer, so only done as test.

I copied 5.19.17-300.fc37.x86_64 from the F37 installation to the F36
installation:
# ls -Gg /boot/ini*19.17*
-rw------- 1 19015128 Oct 25 19:11 /boot/initramfs-5.19.17-200.fc36.x86_64.img
-rw------- 1 34070416 Oct 25 23:02 /boot/initramfs-5.19.17-300.fc37.x86_64.img
#
The F37 version boots normally. Both installations have identical
/etc/dracut.conf.d/*,
so I have no idea why the F37 is so much heavier, unless there's extra stuff in
it
because F37 is still not yet released.
