Hello,
Anybody know the reason RedHat decided not to support the

cat /proc/cpuinfo

I am testing, (using ayplus kernel) and get the following during bootup:

Disabling lock debugging due to kernel taint
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 ...
Thanks for the feedback.
I guess the only thing I can say is at the start of the kernel boot
it says:
KERNEL supported cpus:
Intel GenuineIntel
AMD AuthenticAMD
NSC Geode by NSC
Cyrix CyrixInstead
Centaur CentaurHauls <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Transmeta GenuineTMx86
Transmeta TransmetaCPU
UMC UMC UMC UMC
Which implies to me that it should work. I have booted up 3 boxes
using acpi=off to see
if that makes any difference. So far they have been up a couple of
days, but I need them to
be up at least a week to have any faith that acpi=off makes any
difference.
