is this still an issue with recent kernels ?

Comment 3 charles17 2017-04-28 06:44:06 UTC

Just updated to 4.9.16.  Please give me some time to watch.
When the problem goes away I will close this bug in a month.

Comment 4 charles17 2017-06-16 05:51:32 UTC

Seems to be fixed.  In fact, I never had it with gentoo-sources:4.9.16
