/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:
http://codepad.org/EqlaTaTS

¿There is an error at build process?

Thank.

This happends only on qemu.
I have test it, in the same way with virtualbox
and it works fine.

¿Any idea?
Thank.

Userland network drivers in netdde need some interface in the kernel
which has not been finished yet, it's available as a patch in the debian
packaging:

https://salsa.debian.org/hurd-team/gnumach/blob/master/debian/patches/70_dde.patch

gnumach however has some drivers, so depending on your VM configuration
(type of emulated card), that can work. With qemu you can use

-net user -net nic,model=rtl8139

to use a card that gnumach can driver itself without netdde.

With rtl8139 device also crash it.
I have tested it, and It works with pcnet device.

Thank you for your help!
