+ libata.force= [LIBATA] Force configurations. The format is comma + separated list of "[ID:]VAL" where ID is + PORT[:DEVICE]. PORT and DEVICE are decimal numbers + matching port, link or device. Basically, it matches
.. Mmm.. not a NAK, but is there also a way to set/change these on the fly? I ask because, on my 4-core test system here, libata enumerates the ports differently depending upon whether I boot with a 32-bit kernel or a 64-bit kernel. Major PITA, that, and it's just the kind of thing that spoils fixed "PORT:DEVICE" module parameters, too. Now mind you, it's more likely the PCI layer that does the reverse order thing, but the end result is that my drives/ports are numbered differently depending upon which kernel I happen to boot with. ?? - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
