Since I had installed 2.6.35 behavior changed a little bit. Now all disks at all controllers are affected.
My guess is, that there are two bugs: The first concern the handling of the MCP55 controller. This could be fixed with 2.6.35. The second bug is a timeing/locking issue when using (multiple) softraid: * recursiv call of sync_buffer (see in trace) * completion of raid sync when the kernel had stated the lost of one or more disks * problem at initialisation: SATA link up 3.0 Gbps (SStatus 123 SControl 320); hard resetting link; failed to resume link (SControl 0); SATA link down (SStatus 0 SControl 0); hard resetting link; ... * When all softraid are stopped, no problems happend for days Actual snip: [74261.120083] sd 6:0:6:0: WARNING: Command (0x2a) timed out, resetting card.
