I mailed glibc's libc-ports mailing list recently about this.


Gentoo's Mike Frysinger was the only one to respond.

If you think there's a chance you might be able to take over the job,
I encourage you to mail libc-ports, as I don't know the answers

It's actually just one non-trivial bug (we hope). Kernel bug 10839.

Also, see http://alphalinux.org/wiki/index.php/Bugs_to_watch

Yes, klausmann subscribed to this list after I told him to recently. :)

Well, he has in the past.

According to marc.info, after a 6 month absence on LKML, he sent a
message yesterday. This absence also coincides with the time he
stopped responding to kernel bug 10893.

No, I don't think this is the problem at all. jcristau, the developer
who told me he didn't care, has at least one alpha.

None of the top tier X.Org developers seem to care at all about alpha.
David Airlie told me he thought some of the problems we'd experience
on Alpha with kernel modesetting would be very similar to problems on
the Itanium, which he has to support. So he would be willing to put a
little bit of effort into supporting Alpha, since the heavy lifting
would already be done for Itanium.

The real problem is that nothing is going to get better in regards to
glibc, it's only going to get worse as long as we have no upstream

Unfortunately, some of the tests either fail or hang the system completely.

This makes me think there are probably some corner cases where glibc
would fail in normal applications.

I attribute this to sellers who try to hit the lottery. That is, they
hope that a corporate server with no back up fails and someone with
access to the company's expense account spends 7000 GBP (as I was
recently quoted for an ES47) to get a replacement immediately.

I assume you mean that currently you can't file Alpha related bugs in
the Fedora bugzilla?

I can (and probably would) counter by questioning the benefit of all
the duplicated effort to make Fedora/Alpha.

Absolutely, but I'm not sure how many would actually do so.

I've probably sent five emails to Ivan Kokshaysky and Richard
Henderson each. Neither has responded to any, even when I offered free
