X crashed in LogVMessageVerb() after resume from suspend

[Connor Imes]

I've been trying to capture this for some time now as it doesn't happen often, but I think I finally got what has been happening to me on occasion. When I open my laptop lid to resume from suspend, I get a black screen and can't switch to a tty.

This is not the same as bug 346404 which I also got a few days ago while trying to get this one.

I captured this backtrace in gdb, and I was not able to use "cont" as X terminated with SIGABRT, unlike in the bug above.

We've fixed a couple bugs, #328035 and #333222, which can occur in situations sort of similar to what you've described. I notice you reported this bug against the beta xserver which doesn't have either of these fixes - please retest after updating to xserver 2:1.6.0-0ubuntu6 and see if you can reproduce the issue.

[Connor Imes (ckimes)]

As I mentioned in the original description, this bug is hard to capture as it happens irregularly. I have not been able to reproduce it recently.

[Bryce Harrington (bryce)]

This looks muchly like a bug we had in the log timestamping code, that we resolved by disabling that patch. The symptoms are very similar too, so I think this is a dupe. If you see the bug again, though, please feel free to reopen.
