https://bugzilla.kernel.org/show_bug.cgi?id=118401 --- Comment #28 from Navin <navinp1912@xxxxxxxxx> --- I get a similar error about ahci "used by field" as 0 only in Virtual Machines like qemu . I assume yours is on bare hardware. Maybe bios mode is set to IDE that is why AHCI is not detected. If you change from IDE to AHCI does it work ? If it still doesn't work Well can you take the latest 4.7 and if that also doesn't work you should contact ahci.c - AHCI SATA support Maintained by: Tejun Heo <tj@xxxxxxxxxx> Please ALWAYS copy linux-ide@xxxxxxxxxxxxxxx on emails. saying you have the latest 4.7 mainline . I guess the issue could be easily resolved by the authors. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
