Hi there, 

I've a p4 HT 3,06Ghz, I've HT enabled in the BIOS and in the kernel :

Linux electron 2.6.10-cj5 #6 SMP Fri Mar 4 02:18:08 CET 2005 i686 Mobile
Intel(R) Pentium(R) 4     CPU 3.06GHz GenuineIntel GNU/Linux .

But it seems that one of my cpus is idle (gkrellm monitor or top) :

Cpu0  : 88.0% us, 12.0% sy,  0.0% ni,  0.0% id,  0.0% wa,  0.0% hi,
0.0% si
Cpu1  :  0.0% us,  0.3% sy,  0.0% ni, 99.7% id,  0.0% wa,  0.0% hi,
0.0% si


I'm actually compiling thunderbird with MAKEOPTS="-j3", so , the second
should be used, shouldn't it ?

Is that a kernel issue ? Could you please explain me what's happening ?

Thank you !

Boris.
