... this time with patch ...
Add support for asynchronous scans to libata
Some of the drivers (AHCI was mentioned to me as a culprit) take a long
time to discover all the devices attached to them. Even for ones which
are relatively quick, if you put a lot of them in a machine, it will
take a long time in aggregate. This can be fixed by adding support for
asynchronous scsi scans, which causes the time-consuming portions of
initialisation to take place in threads.
