Did the machine break while going to sleep, or while coming back from sleep? Is this reproducible say over 10 cycles. Has suspend ever worked in the past, if so which kernel release (cat /proc/version_signature)? Please include any information as to the circumstances leading up to this failure, for example did your battery run out? Did the machine lock up, did any messages come out? If it is reproducible could you try the suspend from VT1, press ctrl-alt-F1, login, and run pm-suspend there. If you could test and report back here that would be helpful.

The sleeping process seems to work fine, the problem arises resuming the machine. Latter process seems never to be completed and stops right after the LCD back-light is turned on (but the screen remains black). At that point, the keyboard seems not to work, for example nothing happens pressing Caps-Lock.
If I resume after a suspend from VT1, the screen is restored but the keyboard still doesn't work, moreover the following message is displayed every 60 - 70 seconds:
BUG: soft lockup - CPU#0 stuck for 61s! [NetworkManager: 3483]
I use kubuntu since 6.10, in the past, on my machine, Suspend/Resume has worked only with Kubuntu 8.04, if I remember fine. If that information is important for you, I can try to test it with a liveCD.

[AlbertH (alberthilbert)]

I confirm that issue is related to NetworkManager. If I kill it before suspending, the resume process is successful. Anyway, restarting NetworkManager after "resume" freezes the system.

After last upgrades, suspend/resume does work. The only remaining issue is the wireless driver (rtl8180) is not loaded on resume and I must launch it manually. However this is a huge improvement for me.
Thanks...

Does this issue still appear in Ubuntu 9.10 or 10.04?
