Hi,
jumping in this thread, I have a glitch with CentOS 4.4 and on a 4Gb system.
it's a HP Proliant DL-380G4, take a look:
[shadow@Barcelona ~]$ uname -a Linux Barcelona.uem.br 2.6.9-42.0.10.ELsmp #1 SMP Tue Feb 27 09:40:21 EST 2007 x86_64 x86_64 x86_64 GNU/Linux [shadow@Barcelona ~]$ free total used free shared buffers cached Mem: 3980132 3520928 459204 0 349764 670916 -/+ buffers/cache: 2500248 1479884 Swap: 8385920 160 8385760 [shadow@Barcelona ~]$
and on a SuperMicro mobo (i586) with 4Gb we have:
[shadow@Sakhir ~]$ uname -a Linux Sakhir.uem.br 2.6.9-42.0.10.ELsmp #1 SMP Tue Feb 27 10:11:19 EST 2007 i686 i686 i386 GNU/Linux [shadow@Sakhir ~]$ free total used free shared buffers cached Mem: 4152000 4088104 63896 0 262452 1540648 -/+ buffers/cache: 2285004 1866996 Swap: 2104504 132 2104372
Well, a x86_64 install can't find the 4Gb and a i586 install can. Ok, it's on different hardware, but it shows that CentOS 4.4 can address the 4Gb withou problem. And we had SLES9 on the same DL-380 hardware and it shows the 4Gb RAM...
Somebody can point me a direction to my lost 150Mb ??
Thanks,
Antonio.
