I am using the egcs-1.1.2 from ralf for doing compiles, I think that
you have a more modern compiler, if so, I will be happy to download.

PRid show before.

Corruption is that when I do a ssh to that host, I got parts of
/proc/ksyms into the console.

mine in 32bits is stable, don't crash under load (not very high load
yet).  But in 64bits (with exactly the same userland) got losts of

Already found a couple of problems in c-r4k.c send to the list, and
now a couple of problems in sgiseeq.c and sgiserial.c.  Notice that I
am running that machine with nfsroot, i.e. I don't have basically more
devices than the serial console and the network card.  No real console
support and not harddisk support either.

If you have any patches, I will like to take a look.

Later, Juan.
