Hello,
I tested libata-dev#promise-sata-pata branch, then I saw Mikael
Pettersson's patch, which kind of obsoleted the testing.
So I did libata-dev#upstream too.
Nothig bad happened yet, after about 1h30 of test for each kernel.
bonnie++, dd, untar, mke[23]fs.
dm striped + linear from sda(20GB) & hdd(30GB)
I merged the two branches with linus's tree at
a8b3485287731978899ced11f24628c927890e78
before building them. Clean merge for promise-sata-pata, slight
automerges for #upstream)

The only diff for libata-dev#upstream boot:
ata1: SATA link down (SStatus 0 SControl 0)
Is this expected, harmless, or what ?
Can someone explain me why scsi reports its deveices 2 times ?
This is SMP hw.
