Looks like that patch was just removed in 4.9.75-30 which I just upgraded this system to: http://cbs.centos.org/koji/buildinfo?buildID=21122 <http://cbs.centos.org/koji/buildinfo?buildID=21122> Previously I was on 4.9.63-29 which does not have this problem, and

have the ldisc patch. So I guess the question is for Johnny, why was it removed? In the meantime, I'll revert the kernel and follow up if I see any further problems.
IIRC the patch has been removed from the spec file because it has been merged upstream in 4.9.71.
The IRC discussion I found in my log indicates that it was removed because it didn't apply cleanly due to changes when updating to 4.9.75, yet I don't think anyone independently validated that the changes made are equivalent to the patch that was removed. I was never able to reproduce this issue, so I didn't investigate it myself.
Sounds like the patch is still needed :)
Anyone up to re-porting it to 4.9.75+ ?
It looked, at first glance, like 4.9.71 fixed it .. I guess not in all cases
I'm happy to do testing here if anyone's able to help with a patch, does look like reverting to 4.9.63-29 solved it for me in the interm.
