It crashes when SSHD starts, the serial console GETTY hasn't started up yet so I can't even log in to run those commands Christoph. All I can do now is bisect and then try to figure out what about the guilty change might cause the problem. This is on a 64-cpu sparc64 box, and fast cmpxchg local is not set, so maybe it's one of the locking changes. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
