r343567 merges the PAE vs non-PAE pmap headers for i386 freebsd. After bisection and dealing with the drm-legacy-kmod fallout, I bisected /usr/src to r343567. Building world and a GENERIC kernel and the minimum set of ports to start Xorg on my Dell Latitude D530 laptop, results in a black screen of death and a locked up laptop (no keyboard, mouse, or video).
A comparison of /etc/log/Xorg.0.log for r343566 (Xorg loads and functions) and r353467 (Xorg black screen of death) shows that /boot/modules/i915kms.ko loads correctly as the log files are identical. Comparing dmesg for r343566 to r343567 shows the following --- dmesg.343566 2019-02-20 08:13:07.727202000 -0800 +++ dmesg.343567 2019-02-21 19:02:24.469562000 -0800 @@ -3,11 +3,11 @@ Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 The Regents of the University of California.

I willing to do whatever is necessary to fix this issue (shorter of mailing the laptop to someone). Is it possible to revert r343567 and move forward? -- Steve _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
