Well, il cleaned my dusty mobo, unplugged and plugged again the sata cables. Now, with or without NCQ, boot time is rather short (~28s). So it seems it was a connection problem. I still have some errors as : ............................................ [ 24.708377] ata6.00: exception Emask 0x10 SAct 0x50400001 SErr 0x4010000 action 0xe frozen [ 24.708385] ata6.00: irq_stat 0x00400040, connection status changed [ 24.708387] ata6: SError: { PHYRdyChg DevExch } [ 24.708390] ata6.00: failed command: READ FPDMA QUEUED [ 24.708391] ata6.00: cmd 60/08:00:78:08:c0/00:00:31:00:00/40 tag 0 ncq dma 4096 in res 40/00:00:78:08:c0/00:00:31:00:00/40 Emask 0x10 (ATA bus error) [ 24.708397] ata6.00: status: { DRDY } .......................................... To be sure, i'll buy some news sata cables. Sorry for the noise and thanks again for having helped me. Regards, -- Jacques > >
