Good news for everyone. As of linux-image-2.6.27-11-generic 2.6.27-11.26 , it seems that these lockups had gone. I installed this kernel package on Jan29th, then rebooted the system with new kernel in the night. On Feb 1st, the RAID1 checks had passed without lockups on the system where they were usually reported earlier (intel+ahci).
