I don't have the full dmesg output however I have put a wealth of info
about this into:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=4216
Basically these do look like "random" segfaults happening any point on
the system and having a variety of effects. The double fault is
particularly worrying as it suggests the problem is kernel or qemu. I've
put a script which tends to reproduce the issue into the bugzilla.
When you say you've seen ld.so faults on real hardware, have you any
more details? Are they happening often? Just ld.so?
I need to know if this is a qemu issue or on real hardware too since the
latter is a release blocker and extremely serious.
Cheers,
Richard
