Jesse-

Thanks for the report. Are you seeing any mal-effects of this? Lost data? Unreadable/unwritable files?

Anything odd in your data? Perhaps a really, really long filename? Or a subdirectory that's many hundreds of directories deep?

I haven't found any filesystem data errors yet. I just installed the latest netbook remix on a brand-new Asus 1005HA a few days ago and set my home directory be to encrypted during the installation.

I don't have very many files in my home directory yet. Primarily just 25M or so of bzr/svn trees. I downloaded some things using firefox and scped them to a different system so I don't know how much data was there, but none of them had unusually long names or directory trees deeper than just a few levels.

I just checked a standard Ubuntu Desktop install that I did a few days earlier on a different machine where I'd also configured my home directory to be encrypted during the installation and found the same \\\\\\ messages in dmesg on that machine also.

I've also noticed several of these errors showing up, but haven't been able to nail down what's triggering them yet:
