I don't think such a discussion would be very fruitful [*]. What could indeed be a fruitful discussion would be one about how to avoid shipping an LTS in April with the same stability problems. Such a discussion should take place on the ubuntu-x mailing list (https://lists.ubuntu.com/mailman/listinfo/Ubuntu-x) and not on a bug report. I'm not an expert on xorg, but it seems that the batchbuffer dumps we have sent upstream so far has not triggered any response. From https://bugs.freedesktop.org/show_bug.cgi?id=24825 it seems that what will be needed is that somebody affected by these problems get their hands dirty and do some git-bisecting in order to find where the problems were introduced. Brian Rogers has already started on that bug report, but has only come as far as finding that the problem does not occur with kernel 2.6.30, but is there in 2.6.31-rc1 - irrespective of intel driver version. A first step would be to make sure that this is also the case here, and then try to identify the commit that triggers the freeze. My impression is that this would give the upstream developers something to work on. [*] Here is my impression in case you find it enlightening: First, I don't agree that the intel driver has become flawed recently. It has improved a lot over the recent iterations (we had some freeze bugs like this on i9xx that are now gone). The problem seems to be one introduced in the kernel (maybe a change there triggered a long-existing bug in the driver). Second, there seems to have been very few people testing Ubuntu development releases on i8xx chipsets. There was a call for testing on the ubuntu-x mailing list back in April, with some - but not overwhelming - response. Bug reports for freezes on 845G and 855GM only started ticking in late October, see [1] and [2] for lists. At this time, we were already in final freeze, and since these bugs are hard to fix, it was at the time unrealistic to get it fixed before the release. I think that it was only well after the release that it became clear that a lot of people had this problem.
