-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Tejun, On the 1.5Gbps vs. 3.0Gbps issue I had, the problem was just that I hadn't paid attention to the factory default jumpers... They were set to 1.5Gbps ( I guess they do that for legacy purposes) :) Do you want me to perform any other tests? PS: Are you going to convert the patches for ipr.c & ipr.h so you can apply the libata-tj patches without removing them ? ====================================================== dmesg output for reference (boot with array turned on: ====================================================== .. ..
