Actually 20070803 vs 20070808 doesn't seem to make a difference at boot. Sometimes the boot is clean, sometimes it's not. I removed the 5 good drives, moved the 5 "bad" TB ones to the good slots (i.e. using another swappable backplane, other cables, and another PMP chip (I have two chips: one in port 1 and 2 of my sil3124). Unfortunately, moving the drives to all these new things yielded the same unreliable boot detection so far. I reseated the drives one more time just to be sure. This time they booted ok, but I'm pretty sure it's just the random works/doesn't work thing. I'll rebuild the array overnight and let you know in 8-9h if the array rebuilt and if it can take a mke2fs without blowing up. In the meantime, if you have any suggestions for slowing the drive's speed down to 1.5Gbps, or other ways to debug those random erros I'm seeing, I'm all ears.
