Hello,

I'm preparing to attach a disk.
In the meantime, I've rebuild a 2.6.21-rc4, and got that while booting :

ata1: soft resetting port

Kernel is a stock 2.6.21-rc4 I've just downloaded... I seem to remember
this could be NCQ-related, and my disk should have been blacklisted,
but is this already in 2.6.21-rc4 ?

Paul
