Comment 1 Dave Jones 2005-09-24 06:15:33 UTC 
do you get a msg in dmesg|tail after running this ?
Comment 2 Dave Jones 2005-09-24 06:18:10 UTC 
also, do you get anything extra if you run x86info -v ?
Comment 3 Yan-Fa Li 2005-09-24 06:48:47 UTC 
Ah, dmesg contained this:
Program x86info tried to read /dev/mem between 850401->850441.We stopped at 850

Comment 4 Dave Jones 2005-09-24 18:23:25 UTC 
ah, I see the problem. the mptable.c is riddled with 32bit'isms.
That's not going to work at all on x86-64.
I'll look at rewriting it for 1.16
Comment 5 Dave Jones 2005-09-24 20:48:58 UTC 
can you try   http://people.redhat.com/davej/x86info-1.16-1.12.x86_64.rpm
and see if that fixes it for you ?
Comment 6 Yan-Fa Li 2005-09-26 00:55:49 UTC 
That's better.  Here's the output, not as fancy as on a P4 but at least it works
now.  Thanks.


# x86info -v
