Reboot may be easier. Looking at /usr/src/sys/arch/i386/i386/machdep.c,
there's a Geode-specific reset operation used, but there's a chance it
is an SC1100-only function that won't work on a plain Geode system.
If that's the case, and seeing as you appear to have a standard PC
keyboard controller (which is used to reset normal systems but is
absent from some Geode boards, notably WRAP, hence the alternative
function), you can try editing this file and commenting-out
"cpuresetfn = natsem6x86_cpureset;" from natsem6x86_cpu_setup()
and rebuilding the kernel; this way it will use the normal PC methods
instead.
If this does the trick, the outl/outb are probably hanging your
system, in which case the natsem6x86_cpu_setup needs to do additional
CPU detection and only use the alternative reset function on SC1100
systems.
As pointed out earlier, this does the trick. Now, I try to contribute
a proper patch which discriminates between Geode CPUs in Nokia and
WRAP & Soekris boards in order to call an appropriate reset function.
Using debug kernels customized with 'option CPUDEBUG' does not show an
obvious difference within the '/src/sys/arch/i386/i386/machdep.c'
module between a Nokia (booting from hard disk) and a WRAP (network
booting using PXEboot), see dmesg below.
Would it be acceptable to somehow use the 'bios0' string within
machdep.c to setup 'cpuresetfn' at boot time, or within 'cpu_reset()'
later "at run time" in order to discriminate Nokia motherboards from
WRAPs and Soekris' ?
Or, do I overlook some parameter that would allow to discriminate
those motherboards within machdep.c?
Or finally, more radical, should the setting of the global variable
'cpuresetfn' be postponed to where the motherboard / BIOS is detected,
and not prematurely in the CPU detection stage in machdep.c?
Thanks in advance for your guidance,
Rolf
