(Originally reported to port-mips@netbsd.org[1] and was
suggested to file a bug report so here we are.)
When trying to install NetBSD on my Loongson2f machine (Lemote
Yeeloong) using the 9.2 or current installer, the sysinst will
segfault when trying to format a NetBSD partition and marking
it active. The exact error message looks like below:
,----
| [ 104.2026388] uid 0, pid 16, command sysinst, on /: file system full
| [ 104.2397136] /: write failed, file system is full
| [ 104.2597050] pid 16 (sysinst): user write of 139472@0x78594000 at 730572 failed: 28

A little bit more info about my disk: I have an ext2 partition
(~2GB) on the disk which is required by the PMON boot loader
for the system for booting the system so it must be presented
in the final partition scheme for this system to be able to
boot. The NetBSD installer was also put here. There was also
an OpenBSD partition taking the rest of the disk space before
I tried to install NetBSD. I've tried the following ways of
repartitioning the disk but all failed when trying to mark the
NetBSD partition active.
* Removing the OpenBSD partition and create a new NetBSD
partition without touching the ext2 partition.
* Directly changing the OpenBSD partition type to NetBSD.
* Remove all partition, recreating the ext2 partition and a
new NetBSD partition.
Note that the sysinst from NetBSD 8.2 installer works without
this issue.
Here are some of the disk information Martin suggested that
may be helpful. Note those information are from the
successfully installed 8.2 system.

On a related note, I have also tried to upgrade from a
successfully installed 8.2 system to 9.2/current using those
installers. As this doesn't require repartitioning the disk,
it didn't trigger the sysinst segfault issue. However, when
trying to download the sets packages, it also failed with a
"disk full" error. When inspecting through shell I found that
sysinst was trying to unpack the content to the ramfs instead
of the disk storing the existing system which caused the "disk
full" error. It doesn't look like the same issue but could be
related.
Hope these information help with debugging the issue and I'd
be happy to provide more info when asked.

>How-To-Repeat:
Using sysinst from 9.2/current installer to partition the disk
and mark the NetBSD partition active. Upgrading an existing
installation also fails with "disk full" as it tries to unpack
data onto the ramfs for the installer instead of the target disk.
