Description Matt McCutchen 2007-06-20 17:28:30 UTC
Description of problem:
My Dell Latitude D620 laptop won't resume from suspend mode.  When I press the
power button to resume it, the display remains off.

Version-Release number of selected component (if applicable):
kernel-2.6.21-1.3228.fc7
pm-utils-0.99.3-6.fc7

How reproducible:
Always

Steps to Reproduce:
1. Panel menu: System -> Suspend.
2. Press the computer's power button.
  
Actual results:
The display remains blank with the backlight off.  The power light is on, the
hard disk light comes on once for a second or two, and the Bluetooth light
flashes continuously (even though I have disabled Bluetooth in the BIOS).

Expected results:
The display comes on and shows the gnome-screensaver password prompt so I can
unlock the screen and continue working.

Additional info:
- I am using iwl3945, but I set SUSPEND_MODULES="iwl3945 mac80211" in
/etc/pm/config.d/unload_modules , and I get a message about iwl3945 being
unloaded when I suspend.  The same behavior happened with the ipw3945 driver.
- Resume worked fine on FC6 kernels with the ipw3945 driver.
- I recently unset my system password in the BIOS.  Before I unset the password,
the behavior on resume was as follows: the BIOS password prompt appears, I enter
the password, and then the display shows the four yellow letters "Linu" in the
top row of the screen on a black background.

I have the same problem

Comment 2 Matt McCutchen 2007-07-16 17:56:47 UTC
Manmathan, what model of computer and versions of software are you using?

Comment 3 Matt McCutchen 2007-07-24 01:36:04 UTC
I tried the recently released kernel-2.6.22.1-27.fc7 and the problem went away.
 Thus, I conclude that the bug was in kernel-2.6.21-1.3228.fc7; I'm changing the
component accordingly.  Alas, I can't use the new kernel because it does not
recognize my wireless card, which is a more serious problem for which I will
file a separate bug.

Manmathan, if you see the problem again with kernel-2.6.22.1-27.fc7, please
comment and I will reopen the bug.

Never mind, bug 249253 purports to solve this.
