Hi, I'm using CURRENT r201138 on my machine with Xorg and with debugging. If I trigger a panic with sysctl debug.kdb.panic=1 under Xorg, my system simply hangs. If I trigger it under the console, it works and I get a textdump. If I do "conscontrol delete ttyv0" before triggering the panic, I also get a textdump under Xorg. Is this maybe a rough edge of the new TTY layer?
