Hi Peter, After running the test with the patch you provided, i observed an oops message which was at the top of the these soft lockup message and the oops is the same as the oops reported at http://lkml.org/lkml/2007/9/24/107. And when i applied the patch for the oops proposed at http://lkml.org/lkml/2007/9/25/57 the oops as well as the soft lockup's are not seen. -- Thanks & Regards, Kamalesh Babulal, Linux Technology Center, IBM, ISTL. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
