Hello, I have an AlphaStation 200 4/233 running FreeBSD 4.0-RELEASE, XFree86 version 3.3.6 with a Diamond Stealth 3D 3000 Pro 4MB PCI card for video, and otherwise stock hardware. When I compile, then run XFree86_SVGA on it and kill X from the console I started it on with ^C, the machine instantly crashes with the following error: unexpected machine check: mces = 0x1 vector = 0x660 param = 0xfffffc0000006000 pc = 0x1200bac54 ra = 0x1200bac24 cuproc = 0xfffffe0004379d80 pid = 1328, comm = XF86_SVGA panic: machine check syncing disks... done Uptime: 1d7h25m5s * This problem did not occur when I was running FreeBSD 4.0-CURRENT. What's more, I have not changed any hardware configurations since then. * Tried the machine and found the problems to be reproduceable with both the GENERIC kernel, and any kernel I choose to build. * I tried downloading and re-installing FreeBSD 4.0-RELEASE twice, but to no avail. This problem is perfectly reproduceable. * The "pc =" and "ra =" "curproc =" and "pid =" parameters change between crashes. * While X is running, windows are not drawn properly. For example, xmms will only come up as a large, black rectangle. TWM will not properly draw menus. * After swapping out the Stealth for a STB Velocity 3D, the problems persisted, with the same symptoms. This may not be a telling factor, though, as the same chipset is used on both boards. * As long as XWindows is not running, the machine seems perfectly stable. I've compiled several kernels on it which seem to run fine. * the SRM variable pci_parity is set to off. * If I switch to the S3V server, then the machine will safely exit XWindows, but if I switch between virtural consoles (while X is still running), the machine will hard lock, and a few seconds later, the screen turns blue, and says "CPU HALT CODE = 5" and reboots. * While using the S3V server, windows seem to be drawn and re-drawn properly. Any ideas? Thanks, Dave Haney To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
