Booting Linux on MPC860ADS - crash

[Eisenzopf Thomas]

Hello,

after many troubles and some help from members of this mailing list I
managed to start booting Linux on a MPC860ADS board.

But after the first few messages the system crashes.

I use the 8xxROM from Raphael Bossek with a ROM disk for booting (ext2
filesystem in flash rom). (http://www.s4l.de/powerpc.html)

At the end of this email I attached the output on the serial port. Do you
have an idea what went wrong? Perhaps you can support me with a .config file
for the Linux kernel, perhaps my setting for the kernel compilation are
wrong?

Best regards,
Thomas.
