Was your kernel configured with the CONFIG_FS_ENCRYPTION option? Could you please provide the output of the mount command for the affected file system? Do you recall what sort of code might have been running on this system at the time of failure (for example, kernel build, desktop apps, etc.)? Thanks, Eric
