I spend a lot of time getting Anatoly's new blade installed yesterday but
eventually gave up. While I was able to install Debian Squeeze (Wheezy
wouldn't work either, kernel just reboots akin to the ia64 gcc bug), the
installed system won't boot as the hpsa driver wouldn't load.

Finally got it working with the 4.14.83 kernel plus the Gentoo ptrace patch:

Linux lenz 4.14.83-00001-g6ef2496425e7 #1 SMP Sun Aug 2 19:31:30 CEST 2020 ia64

The machine is running Squeeze now. I will install unstable using debootstrap
on the second disk later today and then the buildd is finally up and running
again.

Great work and great news! So do you also have enabled CONFIG_ZONE_DMA32
for the used kernel in addition or just the Gentoo ptrace patch?

Cheers,
Frank
