Subject: 3.16-rc, ext4: oopses, OOMs after hard powerdown

Hi!

With 3.16-rc3, I did deliberate powerdown by holding down power key
(not a clean shutdown). On the next boot, I got some scary messages
about data corruption, "filesystem has errors, check forced", "reboot
linux". Unfortunately, that made the scary messages gone forever (I
tried ^S, was not fast enough), as system rebooted.

But it seems I have more of the bad stuff coming:

Mounting local filesystems threw an oops and then mount was killed due
to out-of-memory. I lost sda2 (or /data) filesystem. Then both sda3
(root) and sda2 gave me. But there's no disk error either in smart or
in syslog.

(Thinkpad x60 with Hitachi HTS... SATA disk).

I attach complete syslog from the boot up... it should have everything
relevant.

I'm running fsck -f on sda3 now. I'd like to repair sda2 tommorow.

Best regards,
									Pavel
