Comment 1 for bug 736354

When you say:

"On the intel machine using gdb-mutliarch

 gdb-multiarch /bin/ls"

are you actually refering to the Intel copy of /bin/ls ?

This will cause GDB to expect to debug Intel architecture, which does not agree with an ARM architecture being reported by the remote stub.

You should use a copy of the *ARM* binary on the Intel machine when starting GDB ...
