v3.5 can generate spurious SIGBUS. (In reply to comment #1) > v3.5 can generate spurious SIGBUS. Thanks for clarifying this. Which kernel version is the minimum to use intel 2.21.2? I was using 3.8-rc7 before, but encountered a hard-lockup of my machine while watching a video in MPlayer and thus downgraded to 3.5. The theory is that the kernels become more stable with time... If you have a regression in v3.8, we need to get that resolved asap. Is this using mplayer -vo xv or -vo gl? Sorry, there is a known issue in 2.21.2 (I thought was fixed in that release, but it was only fixed in 2.21.3) with a stale mapping being kept around after a window is reparented. So try 2.21.3 / v3.5 and see if that is stable for you. And please do file a regression report for the hang if it persists with 3.8.

I was using -vo xv, but it occurs to me that -vo gl might be better? Can you comment on that? I will switch to 3.8 with 2.21.3 tomorrow and run a few tests/report when I encounter the issue again. Experience says that -xv vo uses less CPU and has fewer artifacts than -xv gl. |

Created attachment 75746 [details] full Xorg log containing the crash I am using the intel driver, version 2.21.2, with Linux 3.5. X just crashed for me, AFAIR it was when switching to the Chrome window, this triggering some rendering operation. I am using libpixman-1-0 0.26.0. Is there a minimum version required for recent intel drivers maybe? My machine has an Intel DH67GD mainboard with an Intel Core i7-2600K CPU. The full Xorg log is attached.
