From 974e0a4537f556867483f493c7f67ccdcb7fc504 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Mon, 4 Apr 2016 12:17:09 -0400 Subject: libata-core: Allow longer timeout for drive spinup from PUIS When spinning up a drive from powered on standby mode (PUIS), SETFEATURES_SPINUP is executed with the default timeout used for any SETFEATURES subcommand, that is 5+10 seconds. The total 15s is too short for some drives to complete spinup (e.g. drives with a large indirection table stored on media), resulting in ata_dev_read_id to fail twice on the execution of SETFEATURES_SPINUP. For this feature, allow a larger default timeout of 30 seconds. However, in the same spirit as with the timeout of other feature subcommands, do not ignore ata_probe_timeout if it is set).
