Re: [Wear-Hard] Re: longrun utility error

what kernel version are you running? occasionally a build of 2.4.20 will
compile but otherwise not actually init either cpuid or msr.  i've also 
had an instance of longrun just refusing to read the device.

a quick check is to cat cpuid.  be sure you have read permision on the node
and you should see somthing like GenuMx86ineTC with some garbage.  

if you don't get anything, try enabling devfs & devfsd and try again.  

devfs will give an idea of what's going on.  if neither cpuid or msr nodes
appear, the kernel isn't loading them properly.  if cpuid is blank, then 
i don't know what to tell you.

if you do see the GenuMx86ineTC string, make sure you have read and write
access to the nodes, as longrun needs to write to the devices.

this should hopefully give you an idea of what's failing and where.
