It is said that the crashes cease when the `nopentium' option is used, so it does appear that something is up.

Yup. But don't forget about the `nopentium' observations. - - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
