Subject: New(?) Athlon bug (reported on gentoo) Date: Sat, 19 Jan 2002 06:36:24 -0700 From: Collins Richey <[EMAIL PROTECTED]> To: lu <[EMAIL PROTECTED]> [ snips from a notice posted on gentoo by Daniel Robbins ] You Athlon users may want to take notice. "...here 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. I tried this and my problems completely disappeared. I immediately contacted some kernel developers, and now Alan Cox and Terrence are going to try to track down this particular bug and add support for autodetecting it to the Linux kernel." Apparently even M$ systems are noticing this. "So, if you are having stability problems (lock-ups, etc) on an Athlon system, particularly with 2.4.18_pre3 which seems to make this bug more prominent, try using the 'mem=nopentium' option which tells the kernel to effectively work around this CPU bug." -- Collins Richey - Denver Area WWTLRD? - FreeBSD 4.4 + xfce + sylpheed _______________________________________________ Linux-users mailing list Archives, Digests, etc at http://linux.nf/mailman/listinfo/linux-users ------------------------------------------------------- -- Peter Ruskin, Wrexham, Wales.
