High load average (top) on HP Proliant ML150 G2

[Jan Isager]

The load average, on a new HP Proliant ML150 G2 is high (1.0) after installation of rhes3 update 5. A driver for SATA Controller has been added (aar81xx.rhes3qu5-i686.img)(it´s from HP driver & support site)under the installation, it was necessary for completing the installation.
Then I reboot the machine, the load average slowly rises to 1.0, takes about 1 min.
I ran the up2date, in hope that bug fix and other package could solve the problem, but it didn’t.
At this time the machine is running on a 2.4.21-32.ELsmp kernel and rhes3 update 7 (Taroon)

From top: load average: 1.00, 1.00, 1.00

I would be glad for any help you can give.

Hi again

I raised this at Red hat support, they said that it was due to a uninterruptible sleep process, and it was the aar81xx wd how was to blaim.

PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND
18 root 15 0 0 0 0 DW 0.0 0.0 0:00 1 aar81xx wd

But since itâ s a HP driver, they (Red Hat) couldnâ t help.

Do you have any ideas how to solve this problem?

It seems that HP discovered an error in there driver, but it´s still not fixed. I found another driver from Adaptec, that solve the problem.
