Do you used a non-default mode?
Perhaps it isn't really helped, but just hide the problem, changing some another race time parameters. I use 80x30 text mode on all screens. >> 2) I still can't enter KDB using Ctrl-Alt-ESC, while booting, after >> booting, after login and while shutdown - nothing happens. >> boot -d enters KDB normally, but the keyboard sequence handler is >> broken, not boot -d. > > Try "<newline>~b".

No, Ctrl-Alt-ESC works for vt at every phase of the system lifecycle. I use Russian keymap for syscons, but Ctrl, Alt, ESC of course are not remapped. I surely remember it works for syscons long time ago. Just to not forget it, I use PS/2 keyboard and have no vt* lines in the kernel config. _______________________________________________ email@example.com mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
