hibernate does not work

[Eyal Oren]

hibernate does not work on breezy (all packages up-to-date 2005/09/05).
it did work on hoary. suspend works (most of the time, sometimes problems resuming)

system goes into hibernate, screen blanks, and writes something to disk, but
does not shutdown.
on startup, the normal boot follows, no resume.

hibernate is enabled in /etc/defaults/acpi-support.
resume is added to /boot/grub/menu.lst

[Matthew Garrett (mjg59)]

Please edit /etc/default/acpi-support and change

USE_DPMS

to false. Attempt a suspend - there should now be more verbose output on the
screen. Does that give any indication? What hardware is this?

[Eyal Oren (ikbeneyal)]

It is an IBM R40.

the output does not mean much to me, I think it might be the wireless PCMCIA
card. I can give you a summary of the messages, if that doesn't help just tell
me what I should look for (or can I save and attach that output somehow?)

and then it hangs.
lspci says 0000:02:00.0 is my Cardbus bridge (0000:02:00.0 CardBus bridge: Texas
Instruments PCI1510 PC card Cardbus Controller)

btw, I looks like standby is resuming fine right now (I don't know what I could
have changed though)

[Matthew Garrett (mjg59)]

Ok. Could you try unplugging the PCMCIA card before hibernating and see if that
helps? If so, I think I've seen the problem - I'll take a look.

[Eyal Oren (ikbeneyal)]

yes. ejecting the wireless card beforehand makes hibernate work indeed.
but resuming does not work.

kernel starts loading and then i'm getting errors with inserting modules. the
system then freezes.

e.g.:
insmod: error inserting /lib/modules/.../console/bitblit.ko -1 file exists
insmod: error inserting /lib/modules/.../console/font.ko -1 file exists

I have exactly the same problem here, but I dont't have andy cards in my
pcmcia-socket. I have an O2Micro Cardbus-Controller in an Acer TM803LMi. Any
suggestions for modules to unload etc.
Here is the relevant device from lspci:

0000:02:06.1 CardBus bridge: O2 Micro, Inc. OZ711M1 SmartCardBus MultiMediaBay
Controller (rev 20)

thx, Lars

This should now be fixed. Please download the latest initramfs-tools and do

sudo dpkg-reconfigure linux-image-`uname -r`

to regenerate your initramfs. Let me know if there are any other problems.

Suspend with inserted PCMCIA cards will be fixed in the next kernel upload.
