First of all, thank you for your support.
Well I was unsure, so I opened the computer, removed the CPU fan.
Processor is a 1.7Ghz, but in the BIOS the CPU clock was 110 where it
should be 100 to be 1.7Ghz.
So yes it was. It's no longer.
Second problem, my CPU fan was controlled by a potentiometer which was
not turned to it maximum. I just removed it and connected the cpu fan
directly to the mainboard. I'm not sure of that, but I'm not sure there
was enough thermal paste between the processor and the fan. So it is
still a future track if the problem reappeared.
Third problem the PC was full of dust. I just cleaned it.
Fourth problem [1], it seems (on purpose in linux source code) that my
processor is not happy with cpufreq governance to ondemand and was
automatically switched to performance.
I modified the default configuration so that it goes in powersave
mode...
In my original email, and before rebooting, I did a dmesg -T... The time
between the CPU related error and the ext4 error is like 17 hours, so
I'm still not sure it's related.
I just rebooted with the new CPU frequencies, and tried everything I
copy a big directory from my (new) ext3 partition to the raid1 ext4
device (which currently now has only 1 device in it ;))
no problem during like 15 minutes...
So I tried something else, because I'm not sure, but I've noticed that
problem occurred more when I'm deleting files, so I run a fdupes on
another big directory of that raid1 ext4 device.
and boum [2]!

$>cpufreq-set -g ondemand

latency of HW, fall back to performance governor

any clue? :/
Few other comments: I have all other FS under ext4 (but the new ext3 i
created this afternoon) and never got problem with them.
My PC originally had only IDE BUS, so I added two PCI controller for
having SATA.
First two disks on the first controller (a big LVM) never got a problem
with ext4
the other two disks on the second controller (different brand) is the
RAID1 device.
