I solved the problem with forcing the scsi controller to U160, and splitting the disks on the both channels to distribute the load. (mine was dual-channel onboard U320 and four Seagate 36G 10Krpm hdds) I've heard that this has something to do with firmware incompatibility on some Seagate SCSI drives and Adaptec U320 controllers, but i don't know if it's true. I haven't found stability issues before and after this change, but i left it at U160 to get rid of these messages.
