Hello guys.
This time I am managing to use the system while in the "middle of the problem".
From the command: "ps aux"

you can notiche the dmesg process with PID 3178 is there waiting for the
chance to read something (might be itself) from disk. It's stuck there
indefinitely.
Trace before launching the dmesg who is stuck there indefinitely:
http://cxg.de/_b32d3b.htm
Trace after launching the dmesg who stuck indefinitely:
http://cxg.de/_eefda9.htm
And yes: the process (dmesg) will not appear in any of the two traces.
I managed to continue using the system by killing rtorrent in time, but it will probably not stay up for long long time.
Or who knows.
But I am available to send you any info while the system is in this state.
I am not subribed to the list, so please CC me.
Enrico
