Anyone having problems with suspend/resume on hp EliteBook 2540p running Ubuntu 11.04, kernel 3.0.0-13-generic-pae #22.

It usually works 9 times out of 10, e.g for a few days, but then resume hangs and a hard reboot is required. It seems that after a couple of suspend/resume cycles the kernel hangs.

I have tried to debug suspend/resume using “resume-trace” debugging but nothing pinpoints exactly what the problem is, except that I suspect the i915 drivers.

As a reference test I have now kept the laptop running w:o suspend/hibernate/restart for over 9 days and I will keep doing that, and it have not locked up. So it is the suspend/resume that causes the problem.

I'm having similar problems with (K)Ubuntu 12.04 (3.2.0-29-generic). In some sense, it's even worse since sometimes the sleep mode does not show up in the “Leave”-Menu after a reboot. I wasn't able to figure out, what causes it, but sometimes sleep mode just doesn't work.

To stop the wifi led from blinking on network activity (really annoying in my opinion as the leds are pretty bright) set led_mode=1 for the iwlagn module (for newer kernels):

sudo -i
echo 'options iwlagn led_mode=1' » /etc/modprobe.d/wlan.conf
modprobe -r iwlagn && modprobe iwlagn

RICOH SmartCard Reader is not working.

works well (kernel 2.6.38)

About the flickering: a work-around is to suspend the machine, then revive it…

Bill Ott, 2011/03/08 22:28

Sometimes the suspend doesn't suspend. It just goes the the logon page with the flicker still present. Good news is, if it does suspend, when you bring it out of suspension the flicker is gone.

Maybe you could help me there, then…

I have just bought this laptop and installed the latest Linux Mint Debian Edition (based on a 2.6.32 kernel) but experienced random (and annoying!) screen flickerings. I then chose to upgrade to a 2.6.37 kernel (first from liquorix and then from experimental) but now, during booting, the screen is backlit, but blank.

I now this bug has been reported, but I can't find any fix. Could you help me there?

Re the wireless driver: I had to install the firmware-b43-lpphy-installer package, as my network controller is the Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) chip, and it works fine.

Charlotte S, 2011/01/25 20:14

Well, never mind. Switching to 2.6.37-999-generic grabbed from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2011-01-19-natty/ seems to work!

Egon Willighagen, 2011/01/13 13:38

System also works fine with Debian Squeeze with a 2.6.37 kernel from experimental. For the wireless drivers install firmware-iwlwifi package.
