As soon as I run the lshw program (from sys-apps/lshw-02.17b-r1), the kernel crashes as follows. [ 29.413339] kernel BUG at arch/x86/mm/physaddr.c:79!

kernel crashes usually mean kernel bugs run it through strace to narrow down the faulting source: # strace lshw and post that log here
Created attachment 398676 [details] strace output This is the strace output. Since gentoo-sources version 3.18.5 is no longer available 3.18.8 has been used to reproduce the bug.
I see some conversation around this involving 3.19_rc. Can you test the latest 3.19, which is 3.19.2 as of this post?
With kernel 3.19.1 everything works fine. With kernel 3.19.2 I get the same error (as far as I can see only the numbers differ). [ 39.719999] kernel BUG at arch/x86/mm/physaddr.c:79!

The strace output is very similar; a lot of calls to mmap2 and munmap then the kernel panic and after that some final system calls.
Is this still an issue with later kernels? If so, have you considered doing a bisect between 3.19.1 and 3.19.2 ?
