Could you please share the partition layout for that system? Which
partitioning method you picked or if you specified some manual
partitioning. Also, please include how many disks are included, of what
size. I will try to reproduce this bug in a virtual machine for further
debugging.

Larry, thanks for these traces. I realized it would have been a good

For grub2 we're still waiting to see the result of running '/usr/sbin
/grub-probe --device /dev/sda1 --target=fs_uuid' under strace, so
setting the status to Incomplete..

I meant to set it to new for the previous data in comment #7 to be
analyzed.

We tried recreated today with a similar Cisco UCS 260 server and it
deployed Precise ok with hwe-t kernel; we did not observe any issue
with grub.

If this bug is no longer reproducible, should it be set to 'invalid'
rather than 'new'?

A couple of things that you might want to check on the affected system:
- can you edit /etc/grub.d/20_memtest86+ to include 'set -x' as the second
line, and capture the output of running 'sudo /usr/sbin/grub-mkconfig -o
/boot/grub/grub.cfg'?
- can you test whether this problem exists when
