The bug appears to be generic and Athlon specific. "Fortunately, I was able to reach Terrence Ripperda from the NVIDIA Linux driver team. He didn't have a solution but did mention that there quite a few Athlon CPUs have a particular bug where the Athlon will corrupt memory if it is using 4Mb page tables with AGP. He said that you could tell the kernel to *not* use 4Mb page tables by passing the 'mem=nopentium' option to the kernel at boot-time, ie via GRUB. " Has anyone seen similar behavior on FreeBSD, and is there a similar boot-time workaround for FreeBSD? -- Collins Richey - Denver Area WWTLRD? - FreeBSD 4.4 + xfce + sylpheed To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
