The c= all trace is attached below. Is it a known issue=EF=BC=9F Look forward to= hearing from you. Thanks in advance! It isn't known to me but I'm rarely testing eCryptfs with SELinux these days. I don't recall any bug reports with a similar call trace, either. You left out some potentially useful information below the "--[ cut here ]--" line and above the "Call trace:" line.
