Very High Load Average on x86_64

Thank you for your answers.

I tried kernel 253.2.1 and it works, I tried also kernel 2.6.4-1.298, downloaded from arjanv
ftp and it works too.


Anyway I have a strange a problem. The Load Average goes very very high without any
particular reason. For example installing the rpm kernel the load goes over 4.00 or copying
a file via samba from Windows machines to Linux the load goes over 6.00 or immediatelly
after boot of Fedora the load reach 2.00 or 3.00.
Is not only a problem of load... the PC is often unusable..... the output of simple command like
ls o ps some time need some seconds to complete.
I found the same problem with older kernel (like 2.6.2-1.74) and with the last kernel
(2.6.4-1.298).


The CPU idle time is always very high and I didn't find any process that consume cpu....
anyway I tried to disable all services, but the problem persist.


I'm not sure if  is it an hardware problem or a software problem.
I tried to change mainboard, ram, hdd controllers with no benefit.

This is my hw configuration:
CPU Athlon64 3200+
512 MB Ram
Controller SATA Promise TX4 (PCI) (I tried also with on-board controller Promise TX2 and SATA VIA)
3 HDD SATA Maxtor 160 Gbyte with RAID software (RAID1 for /boot and RAID5 for others) and LVM2.
Mainboard MSI K8T-NEO (I tried also with Asus K8V)


Probably is some kind of IO problems but I really don't know howto find it and where Kernel spends his time.
I appreciate any kind of help or suggestion! I tried to use kernel profile and oprofile (I downloaded
the x86_64 rpm from arjanv ftp), but I'm not a Kernel developper and I don't know howto use these
tools.


Thanks to all.

The Fedora Core 2 Test 2 is out, but what about the bug id 118002 (or 118128)
and the Kernel 2.6.4-2.275 that fix the problems of this bug?



With test2 out the door, rawhide will open up again in a few days, opening the floodgates for _lots_ of updates. In the meantime, grab kernel updates from http://people.redhat.com/arjanv
