[Xen-users] Load Average 1.00 at idle

["Michael J. Baysek" <mjbaysek@xxxxxxxxxx>]

Since upgrading to the Fedora xen-2-20050823 and associated 
kernel-xen0-2.6.12-1.1447_FC4 packages , I am getting funny reading from 
top, both on dom0 and domU.  Basically, top is reading load of 1.00 when 
machine is basically idle.  

   top - 09:32:12 up 2 days, 22:52,  2 users,  load average: 1.00,
   1.00, 1.00
   Tasks:  56 total,   2 running,  54 sleeping,   0 stopped,   0 zombie
   Cpu(s):  0.0% us,  0.7% sy,  0.0% ni, 96.0% id,  3.3% wa,  0.0% hi, 
   0.0% si
   Mem:     91476k total,    89220k used,     2256k free,    19024k buffers
   Swap:  1572856k total,      548k used,  1572308k free,    18676k cached


Here are some details about the system.

   dom0 kernel:  Linux 2.6.12-1.1447_FC4xenU #1 SMP Fri Aug 26 21:25:28
   EDT 2005 i686 i686 i386 GNU/Linux

In my experience, the previous Xen, running the 1398 FC4 Xen kernels did 
not have this behavior?  Any ideas on what can be done to get my 'real' 
load averages back?
