I had two crashes, or more accurately, freezes, when web-browsing. First was with Firefox on an easy National Weather Service page, I was scrolling down with down-arrow key, and system suddenly froze, no response to keyboard or mouse, display stayed (until I hit Reset). uname -a shows FreeBSD amelia4 11.0-CURRENT FreeBSD 11.0-CURRENT #4 r264310: Thu Apr 10 06:56:03 UTC 2014 root@amelia4:/usr/obj/usr/src/sys/SANDY11NC amd64 NC in kernel name is for NewCons, SC would be SysCons, and I compiled kernel both ways. Second was with Midori, actually twice, on a more complex site, 1040now.net : I checked /var/log/messages, and /var/log/messages.0.bz2, and noticed Apr 15 08:29:52 amelia4 kernel: error: [drm:pid806:drm_do_get_edid] *ERROR* VGA-1: EDID block 0 inva lid. and a few minutes later, Apr 15 08:33:58 amelia4 kernel: error: [drm:pid806:drm_do_get_edid] *ERROR* VGA-1: EDID block 0 invalid. Apr 15 08:33:58 amelia4 kernel: sysmouse: unknown ioctl: t:40007413 Apr 15 08:33:58 amelia4 kernel: sysmouse: unknown ioctl: t:40007413 Apr 15 08:33:58 amelia4 kernel: sysmouse: unknown ioctl: t:80007410 I notice from earlier, and think this must have been the crash with Firefox: pr 14 23:09:18 amelia4 kernel: error: [drm:pid87853:drm_do_get_edid] *ERROR* VGA-1: EDID block 0 in valid. Apr 14 23:09:18 amelia4 kernel: sysmouse: unknown ioctl: t:40007413 Apr 14 23:09:18 amelia4 kernel: sysmouse: unknown ioctl: t:40007413 Apr 14 23:09:18 amelia4 kernel: sysmouse: unknown ioctl: t:80007410 I think these errors must have been the cause of the freeze/crash, and looking for somebody who recognizes what is *ERROR* VGA-1: EDID block 0 invalid. Would I be better with syscons instead of newcons? But then, how would I open a root window for such things as mounting and umounting disks/partitions, and anything else requiring root privilege? Or would I do better on 10-stable? But then if the problem is with the new Xorg, 10-stable would be no stabler than the bleeding-edge 11-head. I am/was in window manager icewm-1.3.8 but think, since the problem occurred with both Firefox and Midori, the problem is with the new Xorg and possibly newcons rather than web browser. Reason for building www/midori was to see if it would be safer than Firefox in terms of stability, and to compare bugs with Midori-0.5.5 on the System Rescue CD. Tom
