Hello,
Anybody know the reason RedHat decided not to support the VIA Eden Processor?
cat /proc/cpuinfo processor : 0 vendor_id : CentaurHauls cpu family : 6 model : 13 model name : VIA Eden Processor 500MHz
I am testing, (using ayplus kernel) and get the following during bootup: Linux version 2.6.32-71.24.1.el6.centos.ayplus.1.i686 (build@6beta32) (gcc versi on 4.4.4 20100630 (Red Hat 4.4.4-10) (GCC) ) #1 SMP Fri Apr 8 17:23:21 PDT 2011 KERNEL supported cpus: Intel GenuineIntel AMD AuthenticAMD NSC Geode by NSC Cyrix CyrixInstead Centaur CentaurHauls Transmeta GenuineTMx86 Transmeta TransmetaCPU UMC UMC UMC UMC UNSUPPORTED HARDWARE DEVICE: Centaur Processor ------------[ cut here ]------------ WARNING: at kernel/unsupported.c:13 mark_hardware_unsupported+0x37/0x40() (Not t ainted) Your hardware is unsupported.

I traced it down to this code, which is not in the standard kernel.org kernel-2.6.32.36: from kernel-2.6.32.36 static void __cpuinit early_init_centaur(struct cpuinfo_x86 *c) { switch (c->x86) {
from 2.6.32-71.24.1.el6.ayplus arch/x86/kernel/cpu/centaur.c
static void __cpuinit early_init_centaur(struct cpuinfo_x86 *c) { mark_hardware_unsupported("Centaur Processor");<<<<<<<<<< switch (c->x86) {
Thanks,
FYI. Replying to my own E-Mail after running 2.6.32-71.24.1.el6 from SL. I can report that I have been having lockups (hangs) on three different via centaur processor boxes. The hangs require power cycling the boxes.
If you take a look on google for "CentaurHauls i686" you will see that this CPU/chipset SAYS it fully supports i686 but it really does not. All of EL6 is i686 and not i586 (which CentaurHauls really fully supports).
I think you are going to have issues with this CPU and EL6 forever. EL5.x should likely be used with this CPU ...
Hello,
does anyone have updates to this page for 6.0. I would like to try to build a 2.6.32.xx kernel.org kernel and see if I still gets hangs on my CentuarHauls boxes.
