I have a dell studio 1569 and just installed linux onto it. I noticed that the cpu has been running high due to systemd-udevd. Going though different posts on the web including this one, I used "udevadm monitor" to help narrow down what was happening, and here is the output:
I first assumed a usb, so I plugged in and unplugged from all ports but soon discovered it did not have the same path as
/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0 (usb), then long story short, while I had
udevadm monitor running, I pushed some keys on my keyboard and noticed that the path was the same for the keyboard (as seen in the picture above), only difference was the beginning of the line had
aKERNEL in front of it instead of
My next test was while I had
udevadm monitor running, I took apart my laptop and disconnected the keyboard to see if those
bind/unbind entrys would stop. But they continued, which makes me now think this is not the keyboard. Can someone know of what else it could be if it is not the keyboard?
EDIT: In case anyone else is running into an issue similar to mine, disabling the bluetooth in the BIOS seems to fix the issue. Refer to this post.
