Seems that enabling SMC debugging slows down system in a way 
that my testcase (playing MP3 via NFS) doesn't work any more.

Looks like CONFIG_PROVE_LOCKING isn't available on ARM? 
PROVE_LOCKING depens on STACKTRACE_SUPPORT && 
LOCKDEP_SUPPORT. These are available only on i386, x86_64 
and MIPS?

Will now try Bruces' proposal and play with IRQ flags.

Thanks

Dirk
