[SOLVED] Arch Linux Something is Wrong With Kernel

Guys i have arch linux installed on my pc i am really new to linux. This is my Probe i'm having problems with kernel espacially on the boot it fails to "apply kernel variables".And i tried LTS kernel i had same problem as in stock linux kernel but my system starts after this error. And sometimes on the boot it scans every usb port even tho they doesn't exists i have 3 usb ports it scans 8 of it. When it does this pc won't boots and i'm forced to shut it from power button. After that if i press power button it boots but still getting failed to apply kernel variables but it still boots.

The output of the following:

# SYSTEMD_LOG_LEVEL=7 /usr/lib/systemd/systemd-sysctl

# means it should be executed as root.  Please also use code tags,  see the BBCode link at the bottom of the reply box.

/etc/sysctl.d/99-sysctl.conf having invalid contents is causing the service failure.

Doesn't get much more specific than this.  Delete those lines.
