In the following thread, the problem can be reliably reproduced after resuming from STR. The BIOS turns on HPA during boot but forgets to do it during resume. http://thread.gmane.org/gmane.linux.kernel/858310 This patch updates libata revalidation such that it considers native n_sectors. If the device size has increased to match native n_sectors, it's assumed that HPA has been unlocked involuntarily and the device is recognized as the same one. This should be fairly safe while nicely working around the problem.

These are used to implement hardware raid. Unfortunately some firmware revisions on these 5723s don't bring the link down when all the downstream ports are unoccupied while not responding to reset protocol which makes libata think that there's device attached to the port but is not responding and retry. This results in painfully wrong boot detection time for these ports when they're empty. This patch quirks those boards such that ahci gives up after the initial timeout. Combined with parallel probing, this gives quick enough probing and also is safe because SIMG5723 will respond to the first try if any of the downstream ports is occupied.
