Post subject:  WARNING: Ramdisk image too big!
Hello,

To get hibernate to work I was trying to install a ramdisk with "echo > /proc/suspend2/do_resume" in linuxrc.

Therfore I did:
Code:
wget http://ftp.us.debian.org/debian/pool/main/i/initrd-tools/initrd-tools_0.1.81.1_i386.deb
dpkg -i initrd-tools_0.1.81.1_i386.deb
cp --reply=yes /etc/modules /etc/mkinitrd/
mkinitrd -o /boot/initrd.gz
The size of initrd.gz however is 4.5M which is to big for my ramfs which is 4M.

Increasing ramdisk=8192 in lilo.conf doesn't help: Kernel panic.
I'm stuck here. And don't know which steps to take next.

Here's my modules file:
Code:
# /etc/modules: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line.  Comments begin with
# a `#', and everything on the line after them are ignored.

Boot off the CD.
Code:
mount -o rw /dev/hda1 /mnt/hda1
chroot /mnt/hda1
cp /boot/initrd.gz.orig /boot/initrd.gz
lilo -v
exit
reboot

Does that mean that the initrd.gz.orig on the CD contains the "echo > /proc/suspend2/do_resume" in its linuxrc?

It means you'll be able to boot your system again. You can try removing some of the modules in /etc/mkinitrd/modules before running mkinitrd again. For instance, pcmica if you have have a laptop, the DVB related items if you are using DVB...

Booting was not the problem. I have a backup ;-)
Even with the initrd.gz image too big the system boots normaly however. But I'm afraid it won't be long until its not. I've tried disabling modules but there are far too much of them and I have no clue which are necessary and which not.
Any hint where I can find out which to use?

I also took another aproach.
I liked the small original initrd.gz which is in gzip format. I even managed to mount it via /dev/loop1 and manualy added "echo ...do_resume" in linuxrc. I then unmounted /dev/loop1, gziped inird and copied it back to /boot/initrd.gz.
I booted without problems however I still get the line that "echo /proc/../do_resume" lacks.
Maybe I'm forgetting something.
