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?

[Jesse Michael (jesse.michael)]

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.

[Jesse Michael (jesse.michael)]

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