>Number: 9143 >Category: kern >Synopsis: syscons of 3.0-RELEASE causes system to crash >Confidential: no >Severity: critical >Priority: high >Responsible: freebsd-bugs >State: open >Quarter: >Keywords: >Date-Required: >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Sun Dec 20 08:10:00 PST 1998 >Last-Modified: >Originator: Pascal Gienger >Organization: Factum Data Network Services, Konstanz >Release: FreeBSD 3.0-RELEASE i386 >Environment: 486DX2, 16 MB RAM, Tseng ET4000 based ISA video adapter. sc driver (syscons) of 3.0-RELEASE. >Description: The sc driver may cause the kernel to panic when using multiple video modes and/or XFree86. >How-To-Repeat: Simple: Type "vidcontrol VGA_80x30" on a virtual tty (you will get 30 lines on your display). Start some applications. Try to switch back to a terminal with the standard mode (25 lines). You will get a long beep and the system crashes. With X11: start X11 via xdm. Wait until xdm login screen appears. Log in, start a memory intensive application (e.g. Netscape Communicator 4.5). Try to switch back to a virtual syscons tty (CTRL-ALT-F1 for example). A long beep, and the system crashes. >Fix: The problem went away when I upgraded the sc driver with the one of 3.0-CURRENT (current from 1998/12/18). You have to tweak a little bit because f the changed inthand2_t (ointhand2_t)-stuff of 3.0-CURRENT. >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
