Hi Diego,

What do you men by freeze:
 * Does it respond to key-strokes ?
 * Does it respond to pings ?
 * Does it respond to the "Num-Lock" key with toggling the "num-Lock" led ?
 * Is the screen blank, or has it the same content as before the freeze ?

It freezed with 0.7.13, ok. Do you had nmi_watchdog and spinlock
debugging at that time on ?

You enabled nmi_watchdog and spinlock debugging for use with 0.7.11 ?
