NetBSD evbmips64el port installation doesn't work with qemu-system-mips64el.

[Utkarsh Anand]

I successfully installed the NetBSD evbmips64el port on gxemul but was unable to install it on qemu. Trying to boot it on qemu takes me to the 'db>' prompt. Here's the output and backtrace:

Here's the command that I used:

Build evbmips64el from source and then launch it from qemu (replace the paths relative to your system):

qemu-system-mips64el -cdrom /extra/evbmips64/distrib/evbmips/cdroms/installcd/NetBSD-7.99.71-evbmips-mips64el.iso -hda /extra/evbmips64.img -kernel /extra/evbmips64/releasedir/evbmips/installation/netbsd-INSTALL_MALTA64 -nographic -M malta

(I've decompressed the kernel)

Here's the output for qemu-system-mips64el --version :

QEMU emulator version 2.7.1(qemu-2.7.1-6.fc25), Copyright (c) 2003-2016 Fabrice Bellard and the QEMU Project developers

This doesn't look like a NetBSD bug. I've attached a screenshot of the working installation using gxemul in the attachments.

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.

[Expired for QEMU because there has been no activity for 60 days.]
