Well.. I have used an old 40 wires cable.... now I have replaced this with a 80 wires IDE cable... no more problems... the tail of dmesg is pctr: user-level cycle counter enabled dkcsum: wd0 matches BIOS drive 0x80 root on wd0a swap on wd0b dump on wd0b the system is up and is running without problems (~6 days)...
