Subject: Broken hd or filesystem access after resume from suspend2disk

Hello,

I'm often having trouble accessing the hd / filesystem after a resume
from  suspend2disk. Sometimes, the machine completely hangs after resume
or it cannot be suspended at all.

Today, I faced the following problem after resuming:

Using wpa_supplicant failed with the message:

wpa_supplicant -t -c /etc/wpa_supplicant/wpa_supplicant.conf -f
/var/log/wpa_supplicant.log -Dnl80211 -iwlan0
wpa_supplicant: symbol lookup error: /lib64/libssl.so.1.0.0: undefined
symbol: RAND_add

ldd `which wpa_supplicant`
        linux-vdso.so.1 =>  (0x00007fffd84b9000)
        libnl.so.1 => /lib64/libnl.so.1 (0x00007fe5ac0bd000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007fe5abeb9000)
        libssl.so.1.0.0 => /lib64/libssl.so.1.0.0 (0x00007fe5abc5d000)
        libcrypto.so.1.0.0 => /lib64/libcrypto.so.1.0.0 (0x00007fe5ab8ad000)
        libdbus-1.so.3 => /lib64/libdbus-1.so.3 (0x00007fe5ab668000)
        libc.so.6 => /lib64/libc.so.6 (0x00007fe5ab2d9000)
        libm.so.6 => /lib64/libm.so.6 (0x00007fe5ab082000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fe5ac30f000)
        libz.so.1 => /lib64/libz.so.1 (0x00007fe5aae6a000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fe5aac4d000)
        librt.so.1 => /lib64/librt.so.1 (0x00007fe5aaa45000)

rpm -qVf /lib64/libssl.so.1.0.0
5........    /lib64/libcrypto.so.1.0.0

-> The libcrypto-library seems to be broken.

In order to check, if there are more broken libraries (after the
resume), I did a md5sum on the complete /lib64 directory to have it at
base for a recheck after a reboot.

The recheck after the reboot showed two more broken files:

cd /lib64
md5sum -c md5sum.out | grep FAILED
libcrypto.so.1.0.0: FAILED
libkeyutils.so.1: FAILED
libkeyutils.so.1.4: FAILED
md5sum: WARNING: 3 computed checksums did NOT match

Apparently, there is something completely broken after resume.

The machine is a MSI CR620 notebook and kernel is 3.1.

Does anybody has an idea how to fix / or further analyze this problem?

Thank you,
kind regards,
