'dmesg' says: [...] ata1-slave: ATA identify retries exceeded ad0: 76319MB <ST380021A> [155061/16/63] at ata0-master UDMA66 acd0: CDROM <GCR-8521B> at ata1-master PIO4 Mounting root from ufs:/dev/ad0s1a ad0s1a: UDMA ICRC error reading fsbn 137023 of 68480-68607 (ad0s1 bn 137023; cn 8 tn 134 sn 61) retrying ad0s1a: UDMA ICRC error reading fsbn 137023 of 68480-68607 (ad0s1 bn 137023; cn 8 tn 134 sn 61) retrying ad0s1a: UDMA ICRC error reading fsbn 137023 of 68480-68607 (ad0s1 bn 137023; cn 8 tn 134 sn 61) retrying ad0s1a: UDMA ICRC error reading fsbn 137023 of 68480-68607 (ad0s1 bn 137023; cn 8 tn 134 sn 61) falling back to PIO mode When I reported this to the STABLE list, my PC was blamed of having some broken communication to my harddisk. Now I wonder if this is indeed the case; or will you also be blamed for having a bad PC :). Regards, Rob.
