The above commit is causing one of my machines to constantly spew ata messages on the console, according to bisect: # first bad commit: [28361c403683c2b00d4f5e76045f3ccd299bf99d] libata: add extra internal command To get it to boot I have to also apply: 88e10092f6a6 ("sata_fsl: use the right type for tag bitshift") The system boots OK and seems fine, except that it's just printing multiple of these per second: ata2: Signature Update detected @ 0 msecs ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: configured for UDMA/100 ata2: Signature Update detected @ 0 msecs ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: configured for UDMA/100 ata2: Signature Update detected @ 0 msecs ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: configured for UDMA/100 ata2: Signature Update detected @ 0 msecs ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: configured for UDMA/100 ata2: Signature Update detected @ 0 msecs And it never seems to stop. The machine is a Freescale/NXP P5020ds, using the sata_fsl driver presumably. Any ideas? cheers
