I think I experienced this with v3.6-rc3 today as well. I thought my ssd
(ocz vertex3) was broken first, but then I saw this mail.

Never happened before on 3.5.something.

I am trying to reproduce it right now, it happened 2 times before I read
the mail, I didnt keep the dmesg. Now it's taking it's time to occurr
again...

Anyway, here comes lspci, and a dmesg (without the problem showing up
yet) is attached.

Cheers,

Dieter
