  • component changed from write-activity (abiword) to x window system

Nice find - reproduced. I suspect a video driver issue.

Test case: open write, hold down the enter key for about 30 seconds so that you are creating a mass of new lines and extending the document canvas more and more. Soon the whole system will hang.

I have not seen the behavior before, so I can not compare. If it is better now, great. Though I managed to freeze the machine while scrolling continiously a long text.

Before, the first scroll frozen the machine.

So now is less likely to hit? Simon, what are your steps to repro?

  Changed 16 months ago by martin.langhoff

Also, please test related bug #11399 -- likely a duplicate, but the repro steps are different...

  Changed 16 months ago by erikos

In my testing I did copy text into the sheet, again and again until I had a large document and then did continiously scroll (finger pressend on arrow keys) until the system hung. I tried to reproduce now another time with the same procedure but couldn't. Tried as well like said in #11399, but still no hang.

Hmmm, we need a second opinion here. Sam -- think you can try to force this one to happen?

  Changed 16 months ago by greenfeld

  • status changed from new to closed
  • next_action changed from test in build to no action
  • resolution set to fixed

This appears to be fixed in 11.3.1 os25; but that is not surprising in that one of the planned changes to the graphics driver was to fix Write so it could handle multipage documents better.

  • status changed from closed to reopened
  • next_action changed from no action to diagnose
  • resolution deleted

Reopening since we do potentially crash in 11.3.1 os25. It just may take a lot of scrolling up and down to do so.

Once a user scrolls off the end of the screen of a document using the arrow keys, there are kernel messages like these for every line shifted on/off screen due to scrolling: 

[ 2563.776426] [GC_gcmkONERROR  ] gckKERNEL_Dispatch(773): status=-3
[ 2563.808668] gckOS_MapUserMemory: address is 3d2678, cannot satisfy alignment request!

  • next_action changed from diagnose to test in build

Please test again in os26, as factory says this is fixed.

  Changed 16 months ago by greenfeld

  • next_action changed from test in build to diagnose

Reproduced just now in os26. Stack trace (if you get one in Xorg.0.log before X dies) is identical to that attached to the ticket from os25.

To easily reproduce, randomly create a few pages of 0-3 characters of gibberish per line, quit Write to save the document, restart Write with said document, and hold down the down arrow key.

Can you please test this rpm and see if it fixes this problem. http://dev.laptop.org/~jnettlet/f14/xorg-x11-drv-dove-0.3.4-4.olpc.armv5tel.rpm

  • next_action changed from diagnose to test in build

In OS28, please test.

  Changed 15 months ago by greenfeld

  • status changed from reopened to closed
  • next_action changed from test in build to no action
  • resolution set to fixed

Seems to be fixed in 11.3.1 os28.
