           Summary: Access to hd or filesystem broken after suspend2disk /
                    resume
    Classification: openSUSE
           Product: openSUSE 12.1
           Version: Final
          Platform: x86-64
        OS/Version: SuSE Other
            Status: NEW
          Severity: Critical
          Priority: P5 - None
         Component: Kernel

After a resume from suspend2disk, the filesystem access is broken, means: some
files do have another md5sum after the resume. Checking the /lib64 directory
with md5sum shows (compared with the status after a reboot from resume), that
the checksum differs for 3 files:

md5sum -c md5sum.out | grep FAILED
libcrypto.so.1.0.0: FAILED
libkeyutils.so.1: FAILED
libkeyutils.so.1.4: FAILED

Sometimes, the resume hangs (returning to userspace doesn't appear at all).

I recognized the problem. because wpa_supplicant crashed with the following
message:

wpa_supplicant: symbol lookup error: /lib64/libssl.so.1.0.0: undefined symbol:
RAND_add

Machine is a MSI CR620:

Reproducible: Sometimes

Steps to Reproduce:
1. Suspend2disk
2. Resume
3. Try to start a program
Actual Results:  
The machine doesn't work reliable any more.

Expected Results:  
The machine should be reliable after a resume as usual.

I can't say, if the problem always happens, because I just can notice it, if a
file is used, which is affected.
