The problem I had with strange behaviour on a Cyrix 686 box appears to
have been fixed by recompiling the kernel with the following settings:-

CONFIG_CYRIX=y
# CONFIG_CYRIX_5X86 is not set
# CONFIG_CYRIX_6X86 is not set
# CONFIG_CYRIX_6X86_VSPM is not set
# CONFIG_CYRIX_6X86_L1_BROKEN is not set

The previous settings, which failed, were:-
CONFIG_CYRIX=y
CONFIG_CYRIX_5X86=y
CONFIG_CYRIX_6X86=y
# CONFIG_CYRIX_6X86_VSPM is not set
CONFIG_CYRIX_6X86_L1_BROKEN=y

I do not know whether its the L1 cache setting or the 6X86 features (the
5X86 features *should* have no effect). There is obviously something
slightly screwy here....

At least one private email to me said that they also had problems with
Cyrix's if any "Cyrix aware" features were compiled into the kernel!

As I understand it, the recognition code, which is compiled in, also sets
the suspend on halt flag, so my processor should be running coolish...
need to have the lid off to check this :-)
