I tried so many things including disabling all io .

Not at all ,i mean not in my case.
As i said i disabled (from the crappy setup itself not @ukc)
power management , for the cpu and pci.
I forgot to say those pc are using the DC adapter not the battery
i set cpu to max perf from the setup, so no speedstep issue :-/

Possible, but what is awesome is that unexplainable fastness at
reboot (aleady set to max perf).
Well i made various test with Mozilla-FF ... it sucks so much, i
saw it set the cpu usage to 90% most of the time (on powermac /
tiger) but hey it s another topic :D

I have 3 T22 (2647 model number) .
I can provide the full dmesg of course (i mailed the entire one to
dmesg@ as usual)

I saw it too (but i decided to remove the pcmcia cage to add
another fan)

This stupid doesn't allow any ACPI that's why i disabled it @ukc.
I ll see if IBM released a new bios.

Well i saw this to solve the "sound to be crappy with pci power

Well , i ll give it a try , but it still would stay a PC :))
