OK: last report before I leave for the weekend. These steps given by
Miguel didnt work for us. What "did" work so far is that we set up a
tftp boot server on labb.detroit, got all the stuff uncompressed on it,
booted miniroot on linux.detroit, setenv diskless 1 then did the
boot -f bootp()labb.detroit:/tftpboot/linux/vmlinux
labb (tftpboot server=126.96.36.199, linux=188.8.131.52)
It boots but as soon as it sees the ethernet driver we get this:
eth0: SGI Seeq8003 08:00:69:07:e6:29 (which is our correct MAC addr)_
Unable to handle kernel paging request at virtual address 00000008, epc
== 880cbc5c, ra == 880cbc3c
The keyboard is still active but the machine is hung. You cannot ping
linux's IP address either.
Looks like we have a problem with this kernel and our hardware but I
couldn't tell you anything more than that.
Anyone have any ideas for Monday morning?
