I've been working with Brady for several days now trying to track down corruption in the vm_page array. I *really* want to know if a VIA chipset patch solves his problem, because it would also explain about a dozen similar bug reports over the last 6 months. (Which would also be good backing to get it into 4.5). -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
