Public bug reported:
When waking up from hibernate on my IBM Thinkpad T42, I get a new
session. All my open sessions are now gone. This leads to potential data
loss (open files that were not saved, etc.)
I do not know if this is of any importance, but I am using encrypted
rootfs and swap based on LUKS.
Additional info:
Here is my /etc/crypttab:
# <target name> <source device> <key file> <options>
root /dev/hda5 none cipher=aes-cbc-essiv:sha256
cswap /dev/hda6 /dev/urandom swap
I do not know if Hibernate saves the RAM to swap. If so, maybe it is a
problem that my swap partition is encrypted with a random key on every
boot (key file=/dev/urandom).
If the disk encryption is the problem, then I think that the user should
at least be warned that he canot wake up from hibernate. Just trashing
the user's data is not very nice :(
