> Hello All.
> I have five Centos 4.4 x86_64 (amd fx-62) boxes with
> 4 gig of Corsair dual channel ram running
> kernel 2.6.9-42.0.10.EL (smp).
> The sixth box is the same except for video card and ram.
> It is using 8gig of GSkill dual channel ram and has
> a very cheap ATI video card in it. This box will segfault
> on boot unless I use noapic acpi=off and nolapic. Even
> with these boot params, the box is not 100% stable. I have
> seen udev segfault right when booting and also when copying
> 15 meg files from /tmp to /usr will lock things up sometimes.
> Yum and Perl have gotten corrupted as well at different times.
> I have 5 fans in the box to vent heat and the BIOS reports
> the CPU running around 90 degrees Farenheit when rebooting.
> I have run memtest86 (from Knoppix 5.1) all night long on the
> 8 gig of ram and it comes up OK. In the past, we have found
> problematic Corsair ram this way. This 8 gig seems to be
> OK as far as memtest thinks.
> Today I will begin removing ram and testing to see what
> happens. Does anyone have some ideas what might be the
> problem? All the other five boxes with Corsair ram work

My "Foundation" verse:
Isa 54:17 No weapon that is formed against thee shall prosper; and
every tongue that shall rise against thee in judgment thou shalt
condemn. This is the heritage of the servants of the LORD, and their
righteousness is of me, saith the LORD.
