Description: After waking up from hibernate, i see lots of "illegal pblock on /dev/sda3" (which is my / partition)
trying to mount shows "no filesystem on /dev/sda3" and cfdisk confirms this.

Additional info:

* package version(s):
kernel 3.3.4-1
pm-utils 1.4.1-4

* config and/or log files etc.
No way to provide any configs, since the filesystem is gone for good.
Hardware: Samsung N220 Netbook

Steps to reproduce:
Here is what i did: Installed arch linux with netinstall, installed, X, xfce, pm-utils, networkmanager and broadcom-wl for my bcm4313 card.
edited syslinux.cfg (resume=/dev/sda2) - this is of course my swap partition
added the resume hook to mkinitcpio.conf and rebuilt initramfs.
Rebooted and logged into X.
triggered a hibernate through xfce's panel item.
After waking up (which worked btw) I wasnt able to do anything. switching to tty1 showed those illegal pblock errors.
Root partition is gone for good, no more filesystem on it.

The first time this happened was on a setup that worked for at least a year (including hibernation) Last time i succesfully hibernated was a few days back.
The 2nd time was a clean setup from scratch.
This task depends upon

I can confirm this and attached part of everything.log. gparted says /dev/sda4 partition type is unknown and all the 12 GB is now free.

This also happens to me. Most of the time, you can restore the corrupted partition by running fsck on it. I tried using a kernel patched with TuxOnIce, but the problem still remains. The problem started yesterday, right after I ran pacman -Syu, although the updates were mainly the xfce-4.10 packages. I use a custom linux-ck kernel version 3.3.4, which worked fine until now.

EDIT: I just reinstalled Arch, 64-bit this time instead of 32-bit, and everything is fine now. It seems this only affects the 32-bit version.

This happened to me, too. I did 'yaourt -Syu' yesterday and also rebooted successfully afterwards. Then I put my computer (MacBook4 with OSX/Arch dualboot) to hibernation. When I woke it up, it did so (i.e. Gnome3 appeared), but it was frozen. I pressed the power button, and that was it, only Grub Shell appeared on trying to run Arch, and the filesystem was not recognized anymore by anything (Grub Shell, SystemRescueCd, SuperGrub2Disk). rEFIt and MacOSX always worked fine, only the Arch partition was killed.

Can confirm on an IBM x40.

shouldn't 3.3.4 be pulled from [core]?
Comment by Daniel (weirddan455) - Thursday, 03 May 2012, 04:21 GMT
There's an update from 3.3.4-1 to 3.3.4-2 in [core] now. Does this fix this bug?

Same problem using i686 3.3.4-1. Hibernate/thaw has been working flawlessly for more than a year. Root partition type set to unknown. Was able to repair the partition by fsck'ing /dev/sda1 and rebooted successfully.

It would be great if someone who has experienced this issue gave 3.3.4-2 a try and reported back. :p
Comment by Otto Allmendinger (OttoA) - Thursday, 03 May 2012, 10:19 GMT
the changelog for 3.3.4-2 says it is a rebuild with different binutils, so it is doubtful that this will have any effect on the bug

Meanwhile 3.3.4-1 is still in [core] and endangering peoples data. I don't get it - why isn't this package being pulled?

[core] contains 3.3.4-2, not 3.3.4-1.

3.3.4-2 solves the freezes we were seeing with 3.3.4-1, and it likely fixes this issue as well.

Just tested both kernels in a virtual machine. 3.3.4-1 can't resume from hibernation (it panics) but 3.3.4-2 works fine.
