There are currently efforts to remove kernel support for older Alpha machines
before EV56 such as the Jensen machines and I was wondering what the current
status of the Linux kernel on your machine was.

Arnd and Paul claim it's broken and no longer works, but not too long ago you
confirmed that Linux 5.14 booted fine on your machine.

Do you have any current data?

Thanks,
Adrian
