IO space is memory-mapped on the Alpha, for portability reasons, some
IO functions quite specific to Intel hardware: iopl and ioperm, are
emulated in the C library. For that the C library need to known the precise
type of Alpha you are using, it can do so either by looking /etc/alpha_systype
which does not exist by default on Debian, or in a better manner by
looking into /proc/cpuinfo.
Maybe if you have an old Milo, or for some other reasons,your
/proc/cpuinfo is not correct. What system type does it report?
Just checked, the libc does not understand ruffian, so if it is the
case, you need to do ln -s EB164 /etc/alpha_systype (the file EB164
does not need to exist), to workaround it, and we should add this to
libc.
The lists of known system type for the C library is:
Alcor
Avanti
XL
Cabriolet
EB164
EB64+
EB66
EB66P
Jensen
Mikasa
Noritake
Noname
Sable
Miata
Tsunami
Rawhide
