(Get the code!)
I am facing something similar. I am already struggling with an issue on this Tyan S3970 (Ubuntu 12.04.03 fully updated), which I am in the process of reporting here:
https:/
I have a pair of system disks (raid/luks) which I am able to boot. I have a pair of data disks (raid) which, when attacked to the sata controller (along with the system disks) lead to a boot failure and drops me into busybox. When I hit control-d to continue the boot, I get stuff that looks like:
BUG: soft lockup - CUP#7 stuck for 23s! [kworker/7:0:469]
BUG: soft lockup - CUP#7 stuck for 22s! [kworker/7:0:469]
INFO: rcu_sched self-detected stall on CUP { 7} (t=15000 jiffies)
INFO: rcu_sched detected stalls on CPUs/tasks; { 7} (detected by 2, t=15004 jiffies)
INFO: Stall ended before state dump start
I have posted pictures of my screen. The first pic is of one boot. The second pair is of a second boot, both using Ctl-D from busybox:

One more piece of information: When I first booted with all 4 disks attached (zero'th boot, if you like), I was successful. I tried to mount the data disks and got a degraded array. That was odd, as I checked and the disk health was reported as good/healthy for both disks. Also, I had been watching the disks and there has been no sign of either disk developing problems. It's when I shut down and rebooted that I found myself getting dropped into busybox and took the first picture.
More information on my machine is located at the above bug report.
