Hi, I have problem with my notebook Fujitsu-Siemens V8010. It has Intel
ICH6M chipset with SATA Controller. And SATA II disk Fujitsu MHT2040BH
with NCQ. If there is request on disk, iowait time of CPU gets to 100%
and whole system gets totally unresponsible. For example apt upgrade (of
average 10 packages totaling 30MB in .debs) gets 30 minutes. CPU iowait
time gets about 95% for whole 30 minutes.
My notebook details:
CPU: Intel Celeron M 1,4GHz
MEM: 256MB 333MHz
HDD: Fujitsu MHT2040BH SATA II, NCQ, 5400rpm, 8MB buffer
SWP: 512MB swap partition
Chipset: ICH6M 82801FBM
GPU: Intel i915GM integrated
kernel: 2.6.19-rc5
SATA Controller/disk driver: ata_piix and ahci tested, but results of
both were almost the same.
dmesg:

I have no other idea how to solve this problem. I'm not sure whether
disk uses correct driver. Friend told me that it may be solved by
increasing RAM (i plan buy additional 1024MB RAM for christmas).
I'm nearly hopeless. I'm trying to find the solution for more than
4months.
Thanks in advance for every hint.

1. does 'mount -o remount,barrier=0 /' change anything?
2. 256MB is really small if you're running modern desktop environment.
Please post the result of 'vmstat 5' while the machine is really slow.

First of all. I've reinstalled Ubuntu and installed Xfce instead of
Gnome. It seemed to me that it was much faster after reinstall. But as
I installed as much programs as I had installed before reinstall it
seems to me that it goes back to problems. Maybe it could by because of
I have running MySQL and PostgreSQL dbs. But they are accessed
minimally-not big queries and not so frequently (Only for use on
localhost). I use for some work postgres and for other mysql.
1. no, that changes nothing. Maybe I just didn't recognised the
difference.
2. if I coldn't find the real problem, I'll buy 1Gig RAM immediatelly.
"vmstat 5" when system is really slow shows following:

Your machine is thrashing. Working set size is over the available
memory and pages are continuously getting dropped and then brought back.
Run top and press 'M' after the list showed up. It will show who are
consuming all the memory. Adding 1G should solve the problem but just
another 256M will make a big difference too.

Well... The problem is solved.
Thanks a lot for your time.
I look forward for additional 1Gig.
Thanks a lot twice more time.
