I included cpuinfo and meminfo. Is there anything else I can provide?
I would like to stress again that T3 was fine (zero failed requests all
the time, and I use the same kernel config for compile), and this T9 is
not. The computer is a hp vectra something. The same happens at a compaq
dl 360 PIII 800.

Do you also use T9?
