Early during booting phase, dmesg shows: [ 0.515651] ata6: SATA max UDMA/133 abar m8192@0xfdefe000 port 0xfdefe180 irq 17 [ 0.833387] ata6: SATA link down (SStatus 0 SControl 300)
But later, it reports lots like the following stanza: [164362.715469] ata6: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen [164362.715474] ata6: irq_stat 0x00000040, connection status changed [164362.715479] ata6: SError: { DevExch } [164362.715490] ata6: hard resetting link [164363.433615] ata6: SATA link down (SStatus 0 SControl 300) [164363.446934] ata6: EH complete Is it related to a disk drive, and if so, is there a way to know which drive is on ata6? PS: There are two drives attached to the system, reported by dmesg like so: [ 0.872490] sd 0:0:0:0: [sda] 156301488 512-byte logical blocks: (80.0 GB/74.5 GiB) [ 0.874828] sd 1:0:0:0: [sdb] 488397168 512-byte logical blocks: (250 GB/232 GiB)
