I started off with trying 2.4 rc4 on my CentOS 7.1 laptop and noticed a single bug. Certainly not a real problem for me at the moment, but I thought I'd report it in case it is worth looking at. Unfortunately, this bug doesn't appear on the existing VM we used for testing. If we're all done with that one, it looks like the kernel may need to be updated, so we may need to use a persistent virtual machine if this is something that needs to be pursued:\r\n\r\nVirtual Machine (working)\r\n3.10.0-123.20.1.el7.x86_64 # 1 SMP Thu Jan 29 18:05:33 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux\r\n\r\nLaptop (tcsch test failed):\r\n3.10.0-229.1.2.el7.x86_64 # 1 SMP Fri Mar 27 03:04:26 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux\r\n\r\n\r\nThe test:\r\n\r\n```\r\nbash           ckpt:PASSED rstr:PASSED;
