It's primarily a "comma" problem, but the capitals do not help and the
"AT YOUR OWN RISK" and "WILL BREAK YOUR SYSTEM" are superfluous.
Any action carried out on a computer is done at the user's risk and if
it does not work with the running kernel it will obviously break the
system.
This might be an improvement:
You can force the installation of this version of udev, WHICH WILL NOT
WORK WITH YOUR PRESENT, RUNNING KERNEL AT THE NEXT REBOOT, by creating
the /etc/udev/kernel-upgrade file.
"force" and "creating" are still somewhat dissociated from each other.
The two ideas would be better expressed in two sentences.
Alternatively:
Please upgrade your kernel before or after upgrading udev. This
version of udev will not work with the kernel you are using at
present. If you do not upgrade the kernel before rebooting it can
lead to an unbootable system.
You can force the installation of this version of udev by creating the
file /etc/udev/kernel-upgrade.

The first two commas are not necessary.
