Answers to important questions on https:/
Q: Have you experienced just one or a series of lockups?
A: I have had several freezes. They occur approximately once a week. They seem to be randomly distributed (e.g. freeze ~ poisson(rate = 1/week)) although I can not rule out that there may be some auto-correlation.
Q: Under what conditions does it seem most likely to reproduce?
A:
* only at boot time: NO
* when resuming from suspend or hibernate: NO
* only when compositing: NO (also occurs in "classic mode")
* when changing resolution or enabling/disabling monitors: NO
* when screensaver or power saving mode kicks in: NO
* visiting particular web pages or loading particular files: PERHAPS, but I can not reproduce it. It has definitely happened multiple times when I was using the web browser (both firefox and chrome at the same time) and it has also happened more than once when a) editing/asking questions at stackexchange site and b) editing figures at lucidchart.com
* switching betwen desktops: NO
* when performing a specific sequence of actions: NO. I have not been able to reliably reproduce this freeze; as suggested at http://
Additional steps:
The file regdump_good.txt has the output from "avivotool regs all"
I tried gathering the output from this command during the freeze (via ssh) but did not realize that I needed to run as root, so the file is empty.
