Fwd: Hibernate works, but resume reboots midway
 
Helo,

This is something I had posted to the debian-users list but didn't get
much response to. Posting it coz I figure laptop users are more likely
to fiddle around with hibernation.

The gist of the problem is that I have a fresh installation of Squeeze
on my Lenovo S10-3 netbook. It hibernates fine (I can see that from the
logs) but upon resuming the system tries to do something and then just
reboots some 15-20 seconds into the process. However, of the dozen or so
times I've tried this so far, one one occasion it did successfully
resume.

If anyone experienced can even give me some pointers on what I could
look for to troubleshoot, that would be great.

Thanks,
Rakhesh

Subject: Hibernate works, but resume reboots midway

Hi,

I am using Squeeze (Linux) on a netbook (an Ideapad S10). Pretty
standard install from the first CD, using GNOME, custom partitions -
with /boot an a primary partition and the rest of the space an encrypted
partition which has LVM on it.

I installed 'pm-utils' and I can get the laptop to hibernate, but when
resuming it asks me for the passphrase and stuff and starts trying to
resume (I can see hard disk activity) and the screen has a blinking
cursor on the top left corner, but about 30 seconds into the process the
laptop just shuts down and reboots.

I tried this a couple of time and always get the same results. But on
one occasion, when I ran 'pm-hibernate' as 'root', resume worked fine.
Subsequent attempts at reproducing this fail though.

I can confirm that the initramfs config files have the file with
'RESUME' set to my swap partition (/dev/mapper/xxx). And the swap
partition's set in '/etc/fstab' too and is active.

>From what I can understand from the 'pm-suspend.log' file (attached),
hibernate seems to be working, but it doesn't even reach the resuming
stage. There's only one instance when it tried to thaw, and that time it
succeeded.

Any ideas or suggestions on what I could do to investigate the further
or fix it?

Many thanks,
Rakhesh

this might not be helpful, but i'm seeing exactly the same behaviour on
my MSI Wind U-100. occasionaly resume from hibernate works, but
generally it doesn't (no matter if hibernated through
gnome-power-manager or pm-hibernate). resume from suspend works fine.
