Yes, I'm running the McKinley kernel.

I didn't got my zx6000 with so much memory. I had the opportunity to
max it out at a very good price, so yes, I updated it, but not
recently. Maybe two years ago?

This may be a track to follow. I don't have a MP card in my zx6000 and
seem to experience less issues than you ;-)

I should add that, since the switch to Mesa 8.0, 3D hardware
acceleration is once again badly broken :-(

While simple GL applications like glxgears run flawlessly, Quake III
demo freezes the system within seconds, monitor enters in sleep mode
and a hard reset finally occurs. With orphan inodes deleted at next

Yes, my Windows install is "up to date" (support was killed in 2004
IIRC), though the 16GB limit is still there.

There is such a website: The Gelato Community --- Linux on Itanium
(http://www.gelato.org) but it seems unmaintained nowadays and the old
forums have disappeared. I remember some interesting discussions there
with David Mosberger or Bjorn Helgaas, circa 2007...
