I used jessie mips on my router in a chroot and was considering going
further, but stretch bumped the ISA requirements so I cannot use it
any longer. Likewise someone on #debian-mips with a Loongson 2f Lemote
laptop recently complained about stretch removing Longsoon support. So
maybe a better approach would be to lower the ISA requirements back to
what was in jessie so folks can use it again in buster?

What CPU is your router? mips r2 is a quite old ISA standard,
they are published in 2002, why your router didn't support it?
The router is a (GPL violating) SAGEMCOM F@ST3864V2 with Broadcom SoC BCM963268 and CPU BMIPS4350 V8.0. This is the default router shipped by
my ISP, I now have two of them and the latest one I recieved new this
year. There are some other devices out there with the same SoC/CPU too:

https://wikidevi.com/w/index.php?search=BCM963268&title=Special%3ASearch&profile=default&fulltext=1
yes, Loongson 2f is only support MIPS II/III.
I have no idea if it is valuable to downgrade mipsel to MIPS II,
at the same time, Loongson 2f has some other bugs, which will ask for gcc/glibc patch, which will slow down the binary on other CPUs.
I guess that is not a good idea then.

I guess most of CPUs support both eb and el.
Please let me know if there is anything I could do to help avoiding the drop.
We need some more build machines, current we use some ER8s,

So the performance and stability are bad.
We also need some more manpower to fix the FTBFS in future.

Sorry to insist, but I thought mips & mipsel in Debian were both
MIPS32r2. So what makes mips32eb so special for MIPS64r6 ?

I'm commenting here from a position of ignorance:
Would SGI hardware make good build machines for the architecture? I'm asking because I have a 3 SGI Octanes I could give away.
Last I checked, stretch kernels did not work on these machines, but I would like
to be wrong.
Is the problem with the linux port, or is it related with Debian's compilation
options?
According to this information from Gentoo https://wiki.gentoo.org/wiki/MIPS/Hardware_Requirements#IP30:_Octane
it should be semi-functional, but that information might be out of date.

Doubtful. Octanes use hundreds of watts and aren't very fast compared
with modern systems. They are indeed big endian, however.

https://wiki.gentoo.org/wiki/MIPS/Hardware_Requirements#IP30:_Octane

The maintainer of T2 Linux (Ren, Cc'd) has a YouTube channel in which
he demonstrated an Octane running a modern (4.8?) kernel he had
patched. I have not seen evidence of those patches going upstream
though. As far as I know his work is in a significantly better state
than that of Joshua's (from Gentoo).

Debian used to have some Broadcom SWARM (BCM91250A) systems. They're
bootable as big or little endian (controllable with a jumper on the motherboard). I have some that I attempt to use for Gentoo, but
they're unstable and their kernel support seems to be totally
unmaintained.
Aurelien, do you know what happened to those systems? I don't see them
listed here: https://wiki.debian.org/MIPSPort#Build_daemons_.26_porter_boxes
(Gentoo would love your hand-me-downs if you're no longer using them :)
