does this apply to SATA disks?
The only SATA devices we support in the core IDE layer are capable of
doing LBA48 DMA anyway.
what's the status of support for 137GB+ SATA disks? it required
libata5 patches from Jeff Garzik before (as of 2.4.21-ac4). I see some
libata is really seperate and for the newer controllers. Its more aimed
at the latest and upcoming hardware which replaces the SATA controller
as we know it today (PATA controller hacked up a bit) with stuff that
looks more like a SCSI controller, with multiple commands, on board
brains etc. Things like the Promise 2037x are the beginnings of this.
thanks for the response but I am still confused - I have a disk that
requires 2.4.21-ac4 + libata5 (from Jeff Garzik), otherwise it does not
recognize anything above 137GB (it recognizes disk as 250GB but all
read/write attempts fail).
2.4.21 vanilla: freezes on boot
2.4.21-ac4 (SCSI_ATA): read/write above 1376GB fails
2.4.21-ac4 + libata5: works (libata changes manually merged in)
is this disk going to work without libata patch?
