Does anyone know how this compares to a recent x86 machine? This seems quite fast for the entire kernel, but I have no idea what typical build times are like.
Raptor does sell a 22-core SMT4 capable CPU, which, Yikes! that's a lot of computing power.
That Blackbird bundle seems like a beast. The Phoronix benchmarks show it outperformed by high end x86 chips though. I wonder if some of that comes down to gcc optimizations because x86 has been around longer.

A fun benchmark would be a Power9 Vs a X86_64 cross compiling the same ARM64 kernel. I wouldn't bet heavily on the Power9...
Slightly OT, but if you limit the playing field to open ISA / fully owner controlled systems, POWER9 is so far out front in terms of performance that it looks like an outlier. ;)
Not that this matters to the end user, but it is still interesting IMO
real 1m55.267s
Run from tmpfs, all protections from Spectre etc. on. Not too bad, really!
We don't support this yet in wlroots, but it's definitely something we want to add, and not a limitation of the Wayland protocol at all.
However, from a libre computing perspective, the WX7100 in my Talos II requires firmware which is non-open, even though it is included in Linux. I imagine that this market would include people interested in reducing the amount of firmware they don't control as much as possible, so for this niche, that is relevant.
For example instead of pull requests, you have mailing lists in which you send patches. You can see more in the website of Sourcehut: https://sourcehut.org
You are a gem and I wish more people were like you.
(I think this applies both to hardware and software products.)
Of course, this is easier said than done, but ultimately this is the core function - are your customers happy or not?
As a CTO you need to prepare the company and your investors for this failure mode. You need to be able to explain to them that sometimes making sure that the product actually works and the existing customers are happy is more important than that sexy new feature of the month. It's not always a very easy balance.
In my experience, even semi-technical people with a more sales/marketing kind of focus in the company often get blindsided by this. It's on us to prep them for this.
It seems like this company learned it the hard way. The key thing is that they did learn.
This particular board was a test escape. A very unique, thankfully singular (so far as I know) test escape, but there's always a chance for that -- the larger failure in my mind was the breakdown in the support process. With our new controls in place (including rapid escalation / RMA of "odd" faults observed by customer) I am confident this won't happen again.
And yes, we're updating tests to catch the newly discovered failure mode. It's an interesting one, the board is a sort of a "zombie" in that if you boot it up by looking at it just right, it'll run stably and pass our stress tests, but it should never have left our factory in that condition due to the other faults. Full stop. :)
Youmu Konpaku is best character. Just gotta love the sword-characters in a bullet-game. Although Flandre was an "extra" endgame boss character, never actually playable IIRC. Really good music for her stage though.

Glad to hear everything is working out for your machine. One thing I'm curious about:
> Installation was a breeze, it compiles the kernel on 32 cores from spinning rust in 4m15s
Is that 8-core / 32-thread CPU? I don't think there's actually a 32-real core CPU available from them. If so, I think that's an impressive speed for 8-real cores.
