[Bug 1837347] Re: guest userspace process core dump after raspi2 kernel boot

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.

If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.

Thank you and sorry for the inconvenience.

  The core dump error can occur at both times, before logging in and after 
logging in, in this case I have given the output after logging in to show the 
initial processes running.

  Also please let me know if I using any kernel flags incorrectly
