4.17.3 mariadb - Page cache invalidation failure on direct I/O

I've seen this message twice now, but I can't find much about it. Under certain load, my mariadb explodes, logging:

Page cache invalidation failure on direct I/O.  Possible data corruption due to collision with buffered I/O!
139891023111936 [ERROR] InnoDB: The OS said file flush did not succeed
File: /var/lib/mysql/xxx.ibd PID: 35623 Comm: kworker/20:2

Is this a bug? Can I work around this? I have never seen this message before, this machine has been running for years without any issues

Was the update to 4.17.3 the first update to the 4.17 series for that system?  Has the system been updated to a newer 4.17 release since?

@loqs, yes that is very likely. As this happens only once every few days, I'm not 100% sure
