>Environment:
System: NetBSD yt.nih.at 5.99.58 NetBSD 5.99.58 (YT) #37: Tue Dec 6 00:14:47 CET 2011 wiz@yt.nih.at:/archive/cvs/src/sys/arch/amd64/compile/obj/YT amd64
Architecture: x86_64
Machine: amd64
>Description:
My /etc/sysctl.conf contains:
ddb.commandonenter=call ddb_vgapost;bt
this worked for some time, but in the last months it stopped working.
When a panic occurs while the console is in X, it _is_ switched back to text
mode, but all that's displayed is a blinking cursor in the upper left corner.
