/hurd/crash after compile gnumach kernel

[Bosco García]

Hello, I have built the gnumach kernel by my own.
After that, I got a crash.
At boot it shown:
/hurd/crash: /hurd/netdde(541) crashed, signal {no:11, code:2, error:2}, excepti
on {1, code:2, subcode:0}, PCs: {0x82020ff, 0x10efe7c}, writing core file.
fsysopts: /servers/socket/2: -i /dev/eth0: (ipc/mig) server died
Error getting interfaces; Computer bought the farm
Can't get list of interfaces.

At reboot, it shown:
/hurd/crash: /hurd/procfs none(27) crashed, signal {no:6, code:6, error:0}, exce
ption {0, code:42014900, subcode:17547264}, PCs: {0x10d9e7c, 0x10d9e7c, 0x10d9e7
c, 0x10d9e7c}, writing core file.

I follow the built process from web, my build script is:

¿There is an error at build process?

Thank.
