HP nw8240 suspend to RAM works only after lid close/open

[Luka Renko]

I am still unable to make suspend to RAM work on HP Compaq nw8240 (model: PY442EA#ABB)

My testing report is here:
https://wiki.ubuntu.com/LaptopTestingTeam/HPNW8240/Kubuntu

I have currnetly installed Kubuntu Dapper Flight 4 (clean install) + all updates up to today.

Suspend part seems to work - machine suspends quickly and LED on power button starts blinking as it should. When I press power button to resume, I just get blank screen. In only one occasion (when running sleep.sh from shell), I got a flashing cursor and I was able to switch consoles (1 and 2) and have seen that sleep.sh was blocked on "modprobe ipw2200" and when I tried to log in on other console, it just blocked after entered password.

I have tried different X drivers ("ati" & "fglrx") and both Ubuntu (GNOME) and Kubuntu (KDE) desktops. Unter Kubuntu it stops even sooner due to klaptopdaemon - see bug 32785.
I have also tried from console (with shuting down kdm/X before), but it still hangs on reboot.

What bothers me the most is that other users (Fangorious) has this working on slighly different model (EG235UC#ABA) - see bug 26386 (has also confirmed this to me over e-mail).

This is sleep.sh output (as far as it get logged when redirected).

dmidecode output

Matthew, this is probably similar to the HP's you have access to; can you check it.

[Matthew Garrett (mjg59)]

What does dmesg say while the modprobe is hung?

[Luka Renko (lure)]

Matthew, I have now clean install of Kubuntu Beta (no updates yet) and cannot get to the point that I would see a text cursor. As I said, I got this text mode with ipw2200 hanging on modprobe only once, and even then I could not login to be able to check dmesg output.

I have tried this now several times from text console (kdm/X stopped) and also with and without wireless (using HW button to turn it off), but could not reproduce anything else than blank screen.

Additional note: disk LED is on when machine hangs on resume.

I will now try to build s2ram utility that is being mentioned in this thread:

[Matthew Garrett (mjg59)]

Ok. The next kernel update may help things here.

[Luka Renko (lure)]

I have tested s2ram (still on 2.6.15-20.30) with init=/bin/bash and still no success. I could not test -a option, as it looks like that /proc/sys/kernel/acpi_video_flags support is missing (added in 2.6.16).

I have also tested with new 2.6.15.21.32 but still no success - this time I cannot even suspend to RAM if I do not unload hci_usb module, which can be unloaded only if I disable wireless/bluetooth.

sleep.sh failing due to hci_usb module

sleep.sh failing due to hci_usb

[Matthew Garrett (mjg59)]

Can you test with the latest kernel and acpi-support packages?

[Luka Renko (lure)]

Matthew, still same result - blank screen after resume. But I can confirm that machine is working after resume, as I have run sleep.sh with "set -x" from console with redirected output and after resume typed "echo THANKS >> sleep.log" and it succeeded. It also rebooted properly when pressed Ctrl-Alt-Del, but did not respond to any console switch.

[Luka Renko (lure)]

stdout/stderr of sleep.sh executed with "set -x"

[Matthew Garrett (mjg59)]

Does triggering the suspend from X work any better?

[Luka Renko (lure)]

It did not work due to bug 32785, but I will try today on my Ubuntu partition (GNOME only), but I need to get it up-to-date.

[Luka Renko (lure)]

I can get my screen back if I simply close the lid and open it again.
I get my console/lock screen back in that case.

It looks like we need to put something in /etc/acpi/sleep.sh (or resume.sh) that is already in lid.sh...

[Paul Sladen (sladen)]

Luka: bug 32785 has been fixed, can you make sure you up to date. If suspend is working then, we can while-list it.

[Luka Renko (lure)]

I have installed fresh copy of Ubuntu Dapper from Desktop CD (20060523.2) and can confirm that suspend to RAM works, but after resume I get the blank screen. Switching consoles or similar does not help
It only helps if I close/open the lid - then I get the screen back, but then I get hit by bug 40808 and I need to manually switch to text console and back to X to get proper resolution in X.

I think it does not make sense to whitelist this notebook as too many workarounds are required to make it work.

[Luka Renko (lure)]

Tested again with clean install of 6.06 LTC release (Kubuntu DVD).
This problem is only with Radeon driver, while proprietary fglrx driver does not have this problem (resumes properly and I get locked screen).

[Luka Renko (lure)]

This is fixed with Edgy RC with updated xorg ati driver.

[Matt Weller (gapplewagen)]

I am having these same issues while running Feisty. I tested with a fresh Edgy install and suspend worked nicely. I then wiped the system clean and installed Feisty and suspend does not work for me. HP nw8240 just as stated above. I have tried by closing lid and manually putting it into suspend mode with the same end result... a black screen upon trying to resume. I have tested with x.org provided ati driver and with fgrlx (both from repos and directly from ATI website).

Feisty regression is tracked under open bug 74877
