Comment 5 for bug 1488672

Brian, I did a git bisect on the affected kernel and I think I found the bad commit causing the kernel panic. Could you try building a kernel with the change in https://lists.ubuntu.com/archives/kernel-team/2015-June/058662.html reverted and see if it solves the problem with Dell's installed Ubuntu 64-bit? That is add the lines with the '-' in front back into step_wise.c? Build instructions are here: https://help.ubuntu.com/community/Kernel/Compile. I find compiling easiest by just editing the Makefile, then make-kpkg --rootcmd fakeroot --initrd kernel_image kernel_headers. Let me know if you need help.

Cheers
