So the problem module should be one of the remaining 60 modules attached as

But now I do not know how to unload them cause I always get the message
"module is in use" - even when system is started in recovery mode.
Especially the "radeon" module which might be a good candidate cannot be
unloaded.
Could you please give me some instructions how to do this?
The radeon module seems like a good place to start.
I would suggest trying hibernation from the minimal recovery shell provided
by the initramfs, as described in the initramfs-tools(8) manpage. It works
roughly like this:
1. Pass "break=modules" on the kernel command line.
2. From the initramfs shell, load enough modules to have a usable
swap partition (that means "modprobe sata_sil" and "modprobe
sd_mod", at least. Enable swap with swapon -a.
3. Load whatever set of modules you want to try (i.e., none, for the
first try).
4. Hibernate (twice, I guess?).
Let me know if you have any questions.
What I would like to mention again (as earlier in bugzilla) is the strange
behaviour that the first suspend to ram always works perfectly fine and the
second one always causes a system hangup
Yes, that is weird but definitely believable. Does suspend to disk behave
the same way?
Thanks, these test results are great. Looking forward to learning the
culprit.

Hi,
followed your suggestions now.
When entering "swapon -a" the message "swapon: /etc/fstab : No such file
or directory" was shown, so I used "swapon /dev/sda5" instead.
Unfortunately I was not able to identify the culprit , after loading all
modules step by step the hibernation check stilled worked fine.
The only error message that came up was on loading module "snd" :
"FATAL: error running install command for snd" with return code 1 .
Regards
Rolf
