https://bugzilla.kernel.org/show_bug.cgi?id=197875 --- Comment #12 from Chuck Burt (chuck.burt+kernel.org@xxxxxxxxx) --- I finally got around to bisecting. I had to do it twice as I identified two issues here. Git Bisect Log 1 - https://bugzilla.kernel.org/attachment.cgi?id=274895 This identifies the commit where processes would full on hang as a result of the drive being connected. 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) -- You are receiving this mail because: You are the assignee for the bug.
