Subject: uswsusp: Cases serious corruption on Ext4, with swap image file

Date: Mon, 12 Oct 2009 16:26:04 +0200

Package: uswsusp
Version: 0.8-1.1+b1
Severity: critical
Justification: breaks the whole system

I am (was) using a file as swap, not a partition, and uswsusp was thus 
configured.
After moving to the new disk, I recreated the swap file, updated the resume
offset value, and recreated initramfs images.
After hibernating, the system resumes fine, but random files are corrupted.
I don't think this is a hardware problem, as of now I noticed file corruption
only twice:
after the first time I tried hibernation, the system wouldn't get out of
rcS because several libraries were corrupted, so I re-copied everything from
the old disk and re-reconfigured uswsusp.
I tried hibernating, and some file in my home dir were corrupted (maybe
somewhere else too, don't know).
I'm not going to try a third time :)
I thought it could be a problem with extents, but I didn't find any report on
the net.
The odd thing is that running fsck.ext4 -f doesn't report errors.
Cheers,

Luca
