    SubjectBroken hd or filesystem access after resume from suspend2disk
    Date
    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)

    libm.so.6 => /lib64/libm.so.6 (0x00007fe5ab082000)

    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.
