Freeze with blinking Caps Lock LED after successful wakeup

[MedO]

Binary package hint: linux-source-2.6.24

I had suspended my Laptop to ram and opened up the lid again some time later. The system woke up and I typed in my password, and noticed Wicd (running in the tray) had not restored my wlan connection. I'm not sure if that's meaningful since I have only installed the program yesterday. I then opened up Wicd and hit the refresh button, and the system froze with a blinking Caps Lock.

System: Toshiba Satellite A100
running Ubuntu 8.04 with proposed-updates (kernel image 2.6.24-17-generic), 64-bit mode
No external devices were connected.

Additional information follows.

I guess dmesg won't show anything extra useful after the reboot, so I have attached part of /var/log/messages instead, I have copied the entire content of /var/log to a temp directory in case you need other information from there later. The log contains a few suspends/wakeups, the crash happened right at the end at 14:10.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

HI,

I recently upgraded to Ubuntu 8.10, and encountered this exact issue. Let me know if and what you'd like me to send in the way off additional information.

Thanks,

Carl Petersen

Hi, having the same issue almost Daily. It happens at random time.

For those of you who have different hardware than the original bug reporter, I'd suggest opening a new bug report for now as this issue is likely hardware specific. We can easily mark bugs as duplicates later on if necessary. I'd also encourage you to report your bug using "ubuntu-bug -p linux" as it will automatically gather important system information and attach it to your new bug report.

@MedO, since you are the original bug reporter, I'd be interested to hear from you if this is still an issue with Intrepid. Please let us know. Thanks.

This bug didn't happen anymore since the original report, neither in Hardy, nor in Intrepid (though I never used Wicd in Intrepid, so that's at least one other factor changed). Also, I sold the laptop in question two days ago, so I can't do any further tests.

[Leann Ogasawara (leannogasawara)]

Thanks for the update MedO. Since you are the original bug reporter, I'm closing this report. Thanks.

This is happening on IBM thinkpad T61 laptop. This behavior happens when i am on Wireless and is used at maximum bandwidth
And on IBM thinkpad R51, this happens after wake-up from a successful hibernate

I have found the above issues only after upgrade to intrepid.
