I agree. It would be sad to see it go.

That's not really what I meant though. I definitely have the time to look
after the architecture as I am also maintaining it in Debian.

What I meant here is that I simply hadn't had the time yet to fully debug
this particular regression that was introduced with 6.1. I did actually
start a bisect and got close to the problematic commit as I got distracted
with my day job.

My plan was definitely to continue debugging the problem in the coming weekend
and at least find the commit that introduced the regression. I always have an
Itanium server ready for testing kernels that I can power on and control remotely
via its built-in management system.

Adrian
