panic during boot

[Allan McRae]

Hi,

I have cross-compiled what I hoped would be a bootable Hurd system but I 
get a panic during boot
(in qemu following grub instructions from 
http://www.debian.org/ports/hurd/hurd-install):

start /hurd/ext2fs.static: panic: thread_invoke: thread 8005fb0 has 
unexpected state 14

A screenshot can be found here:  http://allanmcrae.com/hurd/hurd-boot.png

This is an i586-pc-gnu system compiled with either of these toolchains:

glibc-2.7, gcc-4.1.2, binutils-2.19.1
glibc-2.10.1, gcc-4.4.2, binutils-2.19.1

and using latest git from gnumach, hurd, mig and libpthread.  I can 
provide more information on the cross compile and patches used for the 
glibc builds if relevant.

Any suggestions to try before I attempt debugging this?  As far as I 
understand, I should download a working image (from Debian I suppose) 
then try booting mine up in a subhurd.  Am I on the right track?

(As an aside, building for i686-pc-gnu results in nothing visible 
happening after typing "boot" in grub...)

Thanks,
Allan
