The patch titled libata: change drive ready wait after hard reset to 5s has been removed from the -mm tree. Its filename was libata-change-drive-ready-wait-after-hard-reset-to-5s.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: libata: change drive ready wait after hard reset to 5s From: Stuart Hayes <stuart_hayes@xxxxxxxx> This fixes problems during resume with drives that take longer than 1s to be ready. The ATA-6 spec appears to allow 5 seconds for a drive to be ready. On one affected system, this patch changes "PM: resume devices took..." message from 17 seconds to 4 seconds, and gets rid of a lot of ugly timeout/error messages. Without this patch, the libata code moves on after 1s, tries to send a soft reset (which the drive doesn't see because it isn't ready) which also times out, then an IDENTIFY command is sent to the drive which times out, and finally the error handler will try to send another hard reset which will finally get things working.
