Description Nicholas Stommel 2017-05-18 11:41:10 UTC 
Literally every single time I try to mount an ntfs partition on Ubuntu 16.04.2 LTS running the rc preview of 4.12, I receive this exact same trace message in my syslog telling me that something is wrong. This is a problem, I need to be able to mount ntfs-3g partitions on my machine without data corruption. Any insight or fix would be appreciated.

Comment 1 Nicholas Stommel 2017-05-18 11:50:16 UTC 
See https://bugzilla.kernel.org/show_bug.cgi?id=195809
I wasn't quite sure where to report this one, but this seems fairly important as the warning and message is displayed literally every time an ntfs partition is mounted (through fstab or through the file manager or command line).
Comment 2 Martin Pitt 2017-05-18 11:54:25 UTC 
Sorry, this would need to be fixed between the kernel and ntfs-3g. udisks just calls the command line tools like for any other file system, it has no say in how these actually work.
Comment 3 Nicholas Stommel 2017-05-18 12:02:32 UTC 
My apologies, can you point me to a more specific place where would I file this bug for ntfs-3g and the kernel?
