Total lockup while browsing FF

[Onno Steenbergen]

Hi,

Got gutsy working again..had few problems with supplied rt2x00 driver.. it kept on crashing my ubuntu..
Well removed it and installed ndiswrapper.

Everythings OK.. can connect again to WIFI network.

Browsing on the internet.. then suddenly with no error visible the whole system hangs

This happens when browsing on pages, downloading via firefox
I have check the syslog but cant find anything that looks suspicious

Gutsy 2.6.22-11-generic #1 SMP x86_64
Using all the latest updates

[Onno Steenbergen (osteenbergen)]

Found a strange line in /var/log/messages

Just before the crashes it says
Sep 13 19:41:52 nuxWeb kernel: [ 386.059943] hda-intel: Invalid position buffer, using LPIB read method instead.

the message you see are kernel messages. Reassigning accordingly.

Hi osteenbergen,

Sorry for the extremely delayed response. The following might be of some interest as well: https://bugs.launchpad.net/ubuntu/+bug/134660 .

Also, the Hardy Heron Alpha series was recently released which contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ . Thanks.

This bug report is being closed because we received no response to the last inquiry for information. Please reopen it if this is still an issue in the current Ubuntu release. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Please don't hesitate to submit bug reports in the future, we really appreciate it. Thanks again!

Hi,

I'm getting the same symptoms pretty regularly. I can't actively reproduce it, but probably 1/2 to 1/4 of the times I use my computer it locks up.

You can see I'm getting the LPIB message here:
cat messages | grep LPIB
Jul 7 20:58:29 squelch kernel: [ 73.830973] hda-intel: Invalid position buffer, using LPIB read method instead.
Jul 7 21:11:50 squelch kernel: [ 69.076738] hda-intel: Invalid position buffer, using LPIB read method instead.

Here's what I did last time it happened (30 minutes ago).

1) I booted and left the computer on for about 20 minutes at the login screen while I was doing other stuff
2) I logged in and started Firefox
3) Firefox froze after opening three tabs. I closed it and tried to open it, but it wouldn't open. I tried to open a terminal, but the terminal wouldn't open. I could open Gnome Calculator though.
4) I switched to a VT and logged in. I could use command line programs just fine.
5) I noticed that there was still a firefox process.
6) I did 'killall firefox', it didn't kill it
7) I did 'killall -9 firefox', it didn't kill it
8) I got the PID and did 'sudo kill -9 $PIDHERE'. The process hung.
9) On other VTs I soon discovered that any sudo command wouldn't work

I used ALT-SYSRQ+R-E-I-S-U-B to reboot the computer since I couldn't use sudo shutdown, or the GUI button.

In the past the computer has frozen when I wasn't by it, and when I would come back it would be totally locked up and the fan would be at top speed.

I'd be happy to provide any information developers might find useful. I'm on Ubuntu 8.04 on an AMD 32 bit machine with 2G of RAM.

I also get occasional total system lockups - usually in FF, but the last one just occurred at the login screen.

The final entry in the system log before I reset was the "invalid position buffer" message.

This is on Gutsy. I am one of those people who cannot use Hardy (complete system lock ups every 10 minutes), but Gutsy has always been OK... I'm a bit disturbed to see similar lock ups occurring in Gutsy now.
