Hi,
Something unrelated to the tests I am doing.
I found out that the libsata driver doesn't really cope or likes the idea that you might have a controller without a master drive configured.
In this case on ATA2 I have a CDROM drive, connected as slave. ATA: abnormal status 0x7F on port 0x177 ATA: abnormal status 0x7F on port 0x177 ata2.01: ATAPI, max UDMA/66 ata2.01: configured for UDMA/66
And in another case, I have ATA5 with no drives connected at all: pata_pdc2027x 0000:00:0f.0: PLL input clock 33508 kHz ata5: PATA max UDMA/133 cmd 0xF88597C0 ctl 0xF8859FDA bmdma 0xF8859000 irq 19 ata6: PATA max UDMA/133 cmd 0xF88595C0 ctl 0xF8859DDA bmdma 0xF8859008 irq 19 scsi4 : pata_pdc2027x ATA: abnormal status 0x8 on port 0xF88597DF
Maybe this is purely a cosmetic error where the error code can be translated to something like "no drive attached" or maybe the drivers assume you always configure a master drive on a controller, which doesnt always have to be the case, especialy not with motherboards these days where you get 2 ATA ports + 2 exta raid channels.
