What do you exactly mean? I've seen this on 1TB and 160GB SSD
devices with totally different disk layout.
The output of mkfs.xfs (of xfs_info after it's been created)

Nothing special there.
So far I haven't been able to recreate it. How many runs did you
normally need on 3.1-rc? Note that so far I've run my known working
kernel, I'll test your config plus the drivers I need next.
I had only used 3.0.4 with bonnie++ to reproduce. 3.1-rc was running on
a prod. system.
Sadly i'm also not able to reproduce it reliable on every partition.
Sometimes it works sometimes not. Just retrying does not help. I had to
copy and delete random files from the part. and then start bonnie++ on
it. Perhaps i can give you a dd dump of the partition. But i had to
recreate one. My Intel SSD is now massivly slower than when i started
the tests. No idea why.
