Title:
IRQ/51-SYNA2393 using lots of CPU after suspend/resume
Status in linux package in Ubuntu:
Confirmed
Bug description:
After a suspend/resume cycle (using "deep" suspend mode), the process
IRQ/51-SYNA2393 uses considerable CPU 10+%. Using the trackpad for a
few seconds seems to fix the issue.
I don't normally use the trackpad while docked so it's a bit annoying
to have to remember to use it just to get this problem to go away.
Looks like others have hit the same issue; I found this on askubuntu:
