Use the command: addr2line -e /usr/src/linux/vmlinux -i -a ffffffff812c3b77 Also, if you could give the lines around fs/ext4/file.c (unless it is exactly 4.5-rc6 without any other changes or commit) that would also be helpful. I don't see anything in ext4_release_file() that would obviously be a potential problem after a suspend/reasume. One possibly is that some other piece of code is corrupting memory. > [ 882.459687] CPU: 7 PID: 5299 Comm: dhclient Tainted: G W 4.5.0-0.rc6.git1.1.vanilla.knurd.1.fc23.x86_64 #1 Is it always dhclient which is trying to exit? If you can give a detailed description of your hardware configuration (what devices, what file systems / partitions you have mounted, etc.) that would be helpful.
