Will try the above tomorrow, but I have something around for a quick response. My father worked on the wires in our house (he have an electronic engineer education so you didn't be worried :-) and an older cable reinduced a bypass... ...so I had a "real world test scenario"...:-))) Here comes what I got in dmesg: Linux version 2.4.17-pre5-preempt (root@SunWave1) (gcc version 2.95.3 20010315 (SuSE)) #1 Fre Dez 7 20:39:06 CET 2001 [-] reiserfs: checking transaction log (device 08:03) ...
