I can confirm that using the latest and greatest cdrtools-devel port works around the bug, so it's a definite problem related to mlockall(2). I've burned a cd with a kernel from Aug 19th, and also from Oct 11th and all seems well with this work-around. If there are further patches to try and apply to the kernel to work-around this issue or if people need further print's from gdb from my crash dumps, please let me know! -Jr -- John & Jennifer Reynolds johnjen at reynoldsnet.org www.reynoldsnet.org Structural / Physical Design - ICG/PNG SCD jreynold at sedona.ch.intel.com Running FreeBSD since 2.1.5-RELEASE.
