I just tested the mipsel test image on i386 and x64 hosts with the
same result. Adding -d in_asm shows that the linux kernel is started,
but runs in a loop at some point (timer initialization?). Timer interrupts
are still served (attach cross gdb to running emulation).

Could you already bisect this problem? I did not run these tests for
years.

My standard mips tests use debian mips kernels and show no problems.
