Yes, I will try your configuration when I get back  to the office Monday

Did you have any luck? I just found out something which is almost completely
insane.

For the last few months, I've happily used a 64-bit kernel and have had no
problems whatsoever. About a week ago, I started using virtual machines in
KVM. And today I found that I have exactly the same problem, but only _inside_
the virtual machine. I can't reliably scp a file from the internet to my
virtual machine. It works fine when I scp to the host, it works fine when I'm
on a WPA-PSK network. And it happens even if I tell kvm to emulate e1000, not
only with virtio-net. How strange is that?

And while this is happening, the host is running just fine. The host has a
64-bit kernel with a 32-bit userspace, so if something was wrong with the
32-bit mode of my processor, it would've appeared on the host as well, no?

It's also worth mentioning that if I build openssl with "no-asm 386", scp
works just fine. So it doesn't look like a memory corruption after all. It
seems as if certain CPU instructions didn't work properly if running on a
32-bit kernel with a WiFi adapter doing something. But how can it be
that those same CPU instructions work on a 64-bit host with 32-bit userspace?
At the same time! That's just completely insane, and I can't think of an
explanation. Shall I get a new CPU perhaps? :-)

Please, give me any ideas that you might have.

Regards,
