Created attachment 1446225 [details] [PATCH] libata: Drop SanDisk SD7UB3Q*G1001 NOLPM quirk Here is a patch which I just submitted upstream fixing this.

Created attachment 1446226 [details] [PATCH] libata: Drop SanDisk SD7UB3Q*G1001 NOLPM quirk v2 Here is a v2 which will actually apply cleanly on top of 4.17-rc7
I've added it for the next stable builds (v4.16.14) which *should* arrive in the updates repository before the next atomic build.
