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 KERNEL
or UDEV
.
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?
Here is the output from lsusb -t

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.
