Second suspend hangs with password dialog and frozen keyboard

[Steinar Bang]

Binary package hint: linux-source-2.6.20

The machine is a Dell D610 laptop, with an ATI Mobility X300 screen card (M300 chip set), Dell 1370 TrueMobile WLAN (Broadcom chip set).

On Feisty the first suspend and awakening works find, but when I attempt to suspend the second time the machine works for a while, and then the screen darkens, and eventually the password dialog normally presented at wake up, is shown. However, the keyboard is frozen, so pressing the power button for five minutes is the only way out.

When hibernating I may be able to to several awakenings and hibernates, but eventually I run into the same problem.

I'm always successful in suspending or hibernating, the first time I try.

Suspend/resume worked flawlessly for nearly a year with Dapper on this machine.

On Breezy I only had hibernate.

The system was upgraded from Breezy to Dapper, but the Feisty is a fresh reinstall.

/var/log/kern.log.0 after reboot, after a suspend failed with displaying a password dialog, and with a frozen keyboard.

I was going to send along the kern.log.0 after hibernate failed for me a couple of days later. But the two kern.log.0 files are identical, both wrt. to size and timestamp, and according to diff. So I'm sending just the one. But I've kept the current kern.log file in case that contains interesting stuff as well.

These symptoms looks similar http://osdir.com/ml/linux.swsusp.devel/2004-06/threads.html#00028
(ie. first suspend/resume works. Second suspend fails)

In that case the problem seems to be related to ALSA and 2.6.

After suspending at home and resuming at work today, after logging in, there was a notification banner over the power icon in the tool tray, saying something like:
"Your computer failed to suspend. Check the help file for problems." (the message disappeared again before I could get the exact wording).

Note: this message appeared after a seemingly successful suspend/resume, and the computer has been working without a hitch all day.

This is possibly a HAL bug, and not a kernel bug: Bug #114595 looks very similar

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
