Thanks for the report, although since this appears to be part of a broader testing effort, here are some things that I think would make the reports even more useful:
An indication as to whether or not this is a regression (i.e. do you have a known good build, perhaps even a bisection?)
Either a link to the vmlinux, or faddr2line run on the backtrace. Looking at the above, I can't tell what sparse_init_nid+0x98/0x6d0 actually is.
The exact QEMU command-line you are using, so I can try to reproduce this locally. I think the 0-day bot wraps the repro up in a shell script for you.
Whether or not the issue is reproducible.
Information about the toolchain you used to build the kernel (it happens to be present here because it's in the kernel log, but generally I think it would be handy to specify that in the report).
Please can you provide that information for this crash? It would really help in debugging it.
Sorry for the incomplete bug report.
Thanks for sharing these details. Next time I will include the suggested data points in my email report.
