This have caused no problems what so +1 for me to have it removed PS. The issue was discussed on this list 2016-09-29 to 2016-09-30 between Alexandre, Dietmar, and me. This was a patch by Alexandre witch was related to an issue related to cpu iothread bottleneck with Ceph and scsi-block vs scsi-generic. -- Hilsen/Regards Michael Rasmussen Get my public GnuPG keys: michael <at> rasmussen <dot> cc https://pgp.key-server.io/pks/lookup?search=0xD3C9A00E mir <at> datanom <dot> net https://pgp.key-server.io/pks/lookup?search=0xE501F51C mir <at> miras <dot> org https://pgp.key-server.io/pks/lookup?search=0xE3E80917 -------------------------------------------------------------- /usr/games/fortune -es says: lp1 on fire (One of the more obfuscated kernel messages)
