Jul 15 21:56:12 linux kernel: ata3: nv: skipping hardreset on occupied port

and so on, more output and other details here:

After reboot fsck demands to perform manual recovery.

Resetting link causes SMART's error log filling. Both hard disk (Model=SAMSUNG SP2504C, FwRev=VT100-41, SerialNo=S09QJ1LL402181) and chipset (nForce 430, sata_nv) support 3,5Gb transfer mode. Worked flawless before update and works right now on my other, production system (located on the same physical disk) with kernel 2.6.24.7.

I guess I must be using kernel 2.6.34.1-1 which is the latest for this moment.

I asked to close this bug report because my system started to work today by itself so it has to be a hardware problem. However, my request was denied: A Project Manager has denied the request pending for the following task. Why? ;)
