View Full Version : [ubuntu] Problem with Intrepid suspend/resume on Compaq SR1750NX

I am trying to get Ubuntu working well enough that I can use it for the majority of my computer use. Though this is a desktop unit, it's important to me that I be able to use suspend and resume.

The problem involves one or more of the following symptoms:
1. Suspend doesn't suspend at all. After 30 seconds or so, I get brought back to the password screen just as if the screen-saver had kicked in.
2. Resume works but the wireless connection is dead. In that case, I can reactivate it by disconnecting and reconnecting my USB wireless adapter (Belkin G+MIMO).
3. Getting around problem 2 by editing /usr/lib/pm-utils/sleep.d/10NetworkManager:
# Following 4 lines added by DM 2/24/09 to fix wireless sleep problem:
# /sbin/ifdown wlan0
/sbin/modprobe -rv rt73usb
/sbin/modprobe -v rt73usb
# /sbin/ifup wlan0
These need to be inserted BEFORE resume_nm! I thought ifdown/ifup should help but they don't seem to make a difference.
This fix works some of the time but then this problem:
4. Resume hangs while network manager is attempting to reconnect to the wireless router. (The little balls are spinning around in the notification area.) If I run top in a terminal window, "events/0" is chewing up nearly all CPU time, and top shows that it's consuming in system mode rather than user mode. At this point I usually end up using the power switch to reboot.

This is all with a restricted video driver in use (ATI/AMD proprietary FGLRX graphics driver). It seems to be working fine. Without it, resume presents a black screen.

I have tried the generic 32-bit distro and the one for AMD64, and the results seem to be the same. I would prefer to use the latter if possible (have Athlon 64 processor 3500+).

I have tried enabling both backport and proposed updates, and that doesn't seem to make a difference. Right now I am running kernel 2.6.27-14-generic and GNOME 2.24.1. Have also tried special network-manager updates. Here's my current list of active binary sources:
deb http://archive.canonical.com/ubuntu intrepid partner

deb http://us.archive.ubuntu.com/ubuntu/ intrepid-updates main restricted
deb http://us.archive.ubuntu.com/ubuntu/ intrepid-updates multiverse
deb http://us.archive.ubuntu.com/ubuntu/ intrepid-updates universe

Aside from this one problem, things seem to work wonderfully -- but I'm about to throw in the towel buy a new system with a preinstalled Unix-based OS (that well-known company in California)...

I'm willing to post snippets from console logs, etc., if that might help.

Thanks in advance for any help!

I thought I might as well post part of the system log that demonstrates the problem. This sequence of messages includes from the time of the SUSPEND command, through the RESUME (which worked except for the network being hung & having high CPU activity), then through the shutdown that didn't succeed fully. (I didn't write the times down as things were happening, so perhaps I've included a bit more or less.)

After the GUI exited, there were various system messages on the screen in normal character mode except for the fact that the screen was divided into about 10 vertical stripes (black and white) which were flashing on and off. After the text messages stopped, I had to force the system down with the power switch.

One more strange thing:
If I reboot, suspend and resume seem to work properly the first time after the reboot. It's the second time that things start to fall apart.

I have done quite a bit of searching the Web and tried a couple of things but nothing has helped so far.

Is it unreasonable to expect suspend and resume to work on a desktop machine with a wireless connection?

Problem solved, thanks to this bug record:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/274734

A good answer (work-around) was apparently posted Oct. 8, 2008. It does work on my computer with the generic 32-bit OS; I plan to try 64-bit later.

Everything about it makes sense and is consistent with what I have observed. I have done quite a bit of searching and testing, and I'm a little surprised that it took so long to find a good solution. It seems like this would be a common problem and should be documented as a known issue.

The problem is related to network processes/drivers, not the video driver.

Thanks to everyone who read this thread and thought about my problem.
