As you mentioned I enabled FPU in Fiasco kernel and re-compiled, again I
have the same issue. I couldn't solve the previous issue. The issue that
you mentioned, I disabled FPU in the l4linux configuration, that's why this
wasn't a solution. So now, as FPU is in Fiasco enabled, I don't receive
anymore this failure message, however, the following issue is still
available "sh not tainted". I am not sure but It can be an issue in the
file system (ramdisk-arm.rd). Do you have a stable ramdisk file system for
arm, otherwise I will compile new file system.
