Re: UML broken - runaway loop modprobe binfmt-464c

So you are using 32-bit modprobe binary and 64-bit kernel?
This will not work, since kernel binfmt_elf module checks
if e_machine is EM_X86_64.
Not just 32-bit modprobe - any 32-bit binary on a 64-bit UML will
cause this, I think.
Thanks for the suggestions. After some more investigation and off-list
pointers, it seems the problem is caused because compiling UML for x86_64
doesn't allow you to enable IA32 emulation.
Is this just a case of the Kconfig option being missed, or is there a more
fundamental reason as to why, unlike with the Linux kernel, it's not possible
to run 32-bit apps inside a 64-bit UML?
