Bug Description
I installed Ubuntu Studio 18.04.1 LTS. After the first apt-get update I noticed the following behaviour:
after havig logged in, my USB mouse works normally for about ten seconds, then the cursor starts lagging a lot which makes the mouse pretty much unusable.
The last dmesg always contain lines these: (more in attached file)
[<000000009e659
[<000000009e659
Disabling IRQ #18
Out of frustration & curiosity I disabled most autostart apps (Settings > Session ... > Autostart) and re-enabled them after rebooting. Since then I rarely encounter the lagging cursor. If I open Settings > Mouse & Touchpad and toggle any option on/off the cursor starts lagging.
How can make the cursor work reliably?
Some comment in dmesg mentions "irqpoll" boot option

Please post this in the forums at ubuntuforums.com or at askubuntu.com. Also, please check to see if this is happening with any of the other flavors, especially Xubuntu. For now, I have to mark this bug as incomplete since further information may be required, such as your specific hardware information. Moreover, the bug has to be targeted at a specific package and not the Ubuntu flavor in general, so until there is further information this bug is incomplete.
