I have installed the v4.18.rc8-generic kernel (uname: 4.18.0-041800rc8-generic) Unfortunately the problem remains. Although the driver reports itself as the exact same version as in the Ubuntu kernel (info: MWIFIEX VERSION: mwifiex 1.0 (15.68.7.p154) it produced a slightly different dmesg output which might be of help here. I do not know how to set tags here, I would ask you to set 'kernel-bug-exists-upstream'.
