Hi all,
a bunch of my boxes started showing this on 3.7-rc1 (and maybe earlier):
[ 4.667077] ata4.00: failed to get Identify Device Data, Emask 0x1
[ 4.675071] ata4.00: failed to get Identify Device Data, Emask 0x1
Another one:
[ 3.325371] ata4.00: failed to get Identify Device Data, Emask 0x1
[ 3.488602] ata4.00: failed to get Identify Device Data, Emask 0x1
This last one is a laptop which suspends/resumes so this message happens
each time the driver gets initialized.
[ 1.389734] ata1.00: failed to get Identify Device Data, Emask 0x1
[ 1.395031] ata1.00: failed to get Identify Device Data, Emask 0x1
[16825.339587] ata1.00: failed to get Identify Device Data, Emask 0x1
[16825.345835] ata1.00: failed to get Identify Device Data, Emask 0x1
[16842.294983] ata1.00: failed to get Identify Device Data, Emask 0x1
[16842.300513] ata1.00: failed to get Identify Device Data, Emask 0x1
[23628.820487] ata1.00: failed to get Identify Device Data, Emask 0x1
[23628.825556] ata1.00: failed to get Identify Device Data, Emask 0x1
[23661.555111] ata1.00: failed to get Identify Device Data, Emask 0x1
[23661.560745] ata1.00: failed to get Identify Device Data, Emask 0x1
Grepping points to:
/* Obtain SATA Settings page from Identify Device Data Log,
* which contains DevSlp timing variables etc.
* Exclude old devices with ata_id_has_ncq()
*/
if (ata_id_has_ncq(dev->id)) {
err_mask = ata_read_log_page(dev,
ATA_LOG_SATA_ID_DEV_DATA,
ATA_LOG_SATA_SETTINGS,
dev->sata_settings,
1);
if (err_mask)
ata_dev_dbg(dev,
"failed to get Identify Device Data, Emask 0x%x\n",
err_mask);
}
in ata_dev_configure().
Judging by the logs, it must've came in during this merge window:
