This should have been a single trace, with debugging turned after X was hung. I turned debug on once, grabbed output of dmesg, then rebooted. 1) Run script to launch four windows in rapid succession. 2) Only two windows manage to make it up before X hangs. 3) Switch over to laptop, which is ssh'd into system 4) sysctl hw.drm.0.debug=1 5) dmesg > dmesg.txt 6) Done I may have made a mistake though, and briefly turned on debugging earlier in the session. I'll get another trace this evening when I have time, to double check. p.s. I've put 7.1-STABLE from March 13th on a different partition. I will add in commits until it breaks, to help narrow it down. I'm fairly sure it was something on the 15th or 16th. -- David Johnson _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
