[Voyage-linux] Voyage MPD with kernel/cpu w/o cx8 and cmov

[Andy]

Hi Punky,

thanks for the quick reply.

I have just tried 0.6.5 and it boots without a problem. But that kernel 
doesn't seem to support device nodes like "/dev/hidraw*" or 
"/dev/input/event*" for usb hid keyboard devices. So it doesn't solve 
my problem.


Maybe it helps - here is the output from  cat /proc/cpuinfo:
processor	: 0
vendor_id	: CentaurHauls
cpu family	: 6
model		: 7
model name	: VIA Samuel 2
stepping	: 3
cpu MHz		: 533.285
cache size	: 64 KB
fdiv_bug	: no
hlt_bug		: no
f00f_bug	: no
coma_bug	: no
fpu		: yes
fpu_exception	: yes
cpuid level	: 1
wp		: yes
flags		: fpu de tsc msr cx8 mtrr pge mmx 3dnow
bogomips	: 1066.57
clflush size	: 32
power management:


The message which I get with the MPD kernel while booting is:
...
initrd /initrd.img
  [Linux-initrd @ ..., ... bytes]
This kernel requires the following features not present on the CPU:
cx8 cmov
Unable to boot - please use a kernel appropriate for your CPU.


I don't know why the error message names "cx8" as it is part of the cpu 
flags according to /proc/cpuinfo, but at least cmov remains an 
unsupported feature.

Regards
Andy
