Hi all!
 
Since some time (around switching to kernel 3.4) I am experiencing a long delay of at least 30 seconds when I try to do echo > /sys/power/tuxonice/do_resume in my initramfs.iso.gz.  If I compile kernel with option "Wait for initrd/ramfs to run, by default" unset, the delay happens as well and booting into linux takes a long time.
 
I am using Gentoo with my custom kernel 3.4.4 + TuxOnIce 3.2 from github + CK patchset with BFS scheduler + BFQ I/O scheduler and nothing more.
 
I've noticed that Martin Steigerwald reported recently that the combination TuxOnIce + BFS works well.
 
I would be thankfull for any help.  Maybe some of you encountered similar problem?
 
Thanks,
 
Grzegorz
