linux-next 20120824 introduced regression on Mac mini 2011 - /root partition
gets mounted as read-only and it stays so even when trying to reboot into
previously working kernel. In order to make it work on older kernel again
`fsck` needs to be executed:
----------------------------------------------------------------------
Root partition uses ext4 filesystem on Intel 330 SSD connected to SATA3.
dmesg shows that journaling was disabled:

I haven't bisected to which exactly tree introduces the regression,
but I can tell
that linux-next 20120813 and v3.6-rc3 work fine.

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

Can you pastebin 'dmesg' and 'lspci'?  Did this occur only once, or is
it reproducible?
