Hello,
Anybody know the reason RedHat decided not to support the
VIA Eden Processor?
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 ...
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.
