Since I am just trying to use suspend2 together with evms, I saw, that
there is an implementation in the new linuxrc of evms-2.5.4-initrd.gz.
I am running a 2.6.14-Debian kernel on unstable with the appropriate patches for
suspend2. So I am using:
ii  evms                                              2.5.3-8
ii  evms-cli                                          2.5.3-8
ii  evms-gui                                          2.5.3-8
ii  evms-ncurses                                      2.5.3-8
ii  libevms-2.5                                       2.5.3-8
and evms-2.5.4-initrd.gz

All my volumes are evms-volumes with xfs file systems, grub commandline is:
kernel (hd0,1)/kernel/vmlinuz-2.6.142-md-dm-static-suspend2-asterix \
  ramdisk_size=8192 root=/dev/evms/asterix_root \
  resume2=swap:/dev/evms/suspend2 
initrd (hd0,1)/initrd/evms-2.5.4-initrd.gz

I am suspending (from console, text-mode) to a swap device
/dev/evms/suspend2 and suspending is running fine.

Resuming then fails with (dmesg):
