Both systemd and udev have been observed to trigger backtraces in my tests as well along with other
applications such as sshd and apt, see:

The point is that we have already discovered a bug that affects almost all SPARC variants and we
know it's causing these crashes. This is why I was asking you to test this patch as I'm 99% sure
it will fix those crashes.

You can just cross-compile the kernel from x86_64 using the kernel toolchain:

The systemd discussion has already been held ad nauseam which is why I would like to avoid the
discussion on this list. If someone doesn't want to use systemd, they're free to do so. But
please let's not have that flame war here.

Well, you have the patch and I want your Tested-by because I don't have an OSA2015 machine ;-).
