xen 2.0 testing on amd64(32bit mode) runaway modprobe on lvm disk

[Robin van Leeuwen]

Hi,

I'm trying to get Xen 2.0 testing running on my amd64 (32 bit mode, debian
3.1 i386 sarge installed)
and i'm stuck on using a lvm partition as hda1. I'm getting the following
message during boot of domU:

--------
    ...
    kjournald starting.  Commit interval 5 seconds
    EXT3-fs: mounted filesystem with ordered data mode.
    VFS: Mounted root (ext3 filesystem) readonly.
    Freeing unused kernel memory: 120k freed
    request_module: runaway loop modprobe binfmt-464c

    request_module: runaway loop modprobe binfmt-464c
    request_module: runaway loop modprobe binfmt-464c

and then it hangs. My xend.log shows:

I also tried it with xen2.0 stable but i got the same results...

This is trying to exec /sbin/init (a 32-bit binary), but your kernel
doesn't handle 32-bit binaries.  It tries to modprobe binftm-464c, but
modprobe is a 32-bit binary...

Now, this is a guess: did you turn CONFIG_IA32_EMULATION off?

Rusty.
