Just wanted to point out positive feedback for Albert's patch:
http://lkml.org/lkml/2005/9/15/358
The reason I mentioned Albert's patch in my reply, in that thread, is
that sometimes SATA controllers may not emulate nIEN properly, or may
depend on the device to set (or not) the 'I' bit in the SATA FIS.
This success is an example of why I want to move libata to use
interrupt-driven PIO by default, long term.
We still want to keep the polling code, and perhaps even expand things a
bit so that users with broken interrupt routing (read: no interrupt
delivery for ATA controller) can still use their disks.
Jeff
