[Xenomai-help] Enable I-PIPE - kernel boot hangs in mpc836x_mds

[Xenomai-help] Enable I-PIPE - kernel boot hangs in mpc836x_mds

[Michael Galea]

I'm trying to bring xenomai up on an Freescale mpc836x_mds board. I'm 
using the ipipe-2.6.24-powerpc-2.1-02 branch of the git tree at Denx.

The kernel boots fine with ipipe disabled, nfs root mounting its file 
system.  But as soon as I enable ipipe in the kernel I get..

...
RPC: Registered udp transport module.
RPC: Registered tcp transport module.
IP-Config: Complete:
       device=eth0, addr=10.128.10.234, mask=255.0.0.0, gw=10.128.0.253,
      host=10.128.10.234, domain=, nis-domain=(none),
      bootserver=10.128.10.10, rootserver=10.128.10.10, rootpath=
Looking up port of RPC 100003/2 on 10.128.10.10
irq 33, desc: c02746c0, depth: 0, count: 0, unhandled: 0
irq 33, desc: c02746c0, depth: 0, count: 0, unhandled: 0

And it hangs.  Since this is the place where the kernel usually finds 
its PHY, I might suspect its an issue with that..

I'm currently trying to get Denx's 2.6.20 branch running but its 
freezing after loading the device tree, so I have some issues there.

Can anyone having success with this board report what kernel they are using?

Thanks

Something may be missing in the IPIC code to fully support the interrupt
pipeline too. A dump of /proc/interrupts when the board boots properly would
help here.
