Mmm. Quite. I don't have much information from your report here. Several questions: 1) Can I get a full description of your FreeBSD-current variant, hardware, boot -v log, and copy of your kernel config for this experiment? And your XF86 startup messages, too, for good measure? 2) If your machine's PCI bus is overclocked (i.e., system bus is at 75 or 83 MHz), try it within manufacturer and PCI specifications. 3) These "marching ants"-- are they transient, or do they leave trails in your screen buffer when disk activity ceases? 3) What happens if you try this without X? --jh -- Mr. Belliveau said, "the difference was the wise, John Hood, cgull intelligent look on the face of the cow." He was @ *so* right. --Ofer Inbar smoke.marlboro.vt.us To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
