Subject: Corrupted files after suspend to disk

Hi,

I'm facing a very strange problem on my netbook (Lenovo Ideapad S10)
running Linux 2.6.37.4.
After resuming from s2disk some files are corrupted.
But when I reboot my netbook everything seems good again.

When I saw the problem the first time the ls command segfaulted always.
I did a reboot and it worked again.

A few days later zypper crashed. After a reboot it worked again.
And today ssh crashed. I looked a bit closer and saw it crashed
somewhere within libcrypto.
So I made copy libcrypto and rebooted.
After the reboot ssh worked again but libcrypto and the copy of it hat
a different sha1 sum!
WTF?!

Is this a known issue?

dmesgs and config are attached.

The used distribution is openSUSE 11.4 with suspend-0.80.20100129-7.1
(default from suse).
I'm using ext3 as root filesystem.
What else do you need?
