In the forums I saw a few posts about suspend2-sources spitting out messages over their splash screens, and I was having the same problem. I fixed it by commenting out 2 lines in /usr/src/linux/kernel/power/ui.c. Namely: // if (ui_helper_data.pid == -1) // printk(KERN_EMERG "%s\n", lastheader); I would like to request a "Silent" use flag which patches those 2 lines with comments so it shuts up :)
Nevermind, it was a typo in my hibernate.conf which made it fail to set the userui_program.
