A few people asked whether I could post the program ... it took a while to get sign-off ... but that gave me time to add "branch", "predicate" and half a dozen "application" registers to the mix, plus make it print the name of the register that was nuked (instead of a number that required manual translation). I've tested it by using a debugger to zap one of each class of register that is being monitored to check that it works. http://www.kernel.org/pub/linux/kernel/people/aegl/ia64regcheck.tgz Usage ... compile, and run a few copies. If they all "exit(0)" (which may take a couple of days) the test passed. Otherwise you should see the name of the register printed to stderr, and exit code 1. Apart from the MCA case, I haven't seen it report a problem yet ... but I've only run a few hours. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
