I am still working on this, but may be struggling in addition, with another
bug. This new bug seems to have been noticed in other contexts, so I have
reported it here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1011914/comments/21
In basic outline, I can boot my RAID/LUKS pair of disks, but when I also
attach the RAID pair of data disks, I get dropped into busybox. A
Control-D produces 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
More info at the above link. I will also get your information from a
recent nightly, but right now I'm struggling with 3 failing machines & 4
bugs.
I'l mention that as I'm working on this, have upgraded the BIOS on the
TARO SATA controller so that it along with the system BIOS are the most
recent.
