https://bugzilla.kernel.org/show_bug.cgi?id=197875 --- Comment #16 from Chuck Burt (chuck.burt+kernel.org@xxxxxxxxx) --- Git Bisect Log 2 - https://bugzilla.kernel.org/attachment.cgi?id=274897 This identifies a separate issue (should I file a separate bug for this?) where mounting/unmounting caused error: > Device /dev/sdb3 is already mounted at `/media/temp/[identifier]`. > (udisks-error-quark, 6) Unmounting gives a similar error about being unable to unmount (I can provide the exact error in a bit if you need it). This mounting/unmounting error still exists in the v4.15 kernel and was introduced in the commit isolated in the above bisect (Git Bisect Log 2). -- You are receiving this mail because: You are the assignee for the bug.
