Public bug reported: I am using a Shuttle Barebone SN78SH7 with an onboard graphic card nvidia GeForce 8200. The monitor is connected via HDMI / DVI.
When the system is on minimal workload everything is fine, but when I am starting several cpu intensive tasks, like virtualbox, intensive datatransfer via LAN, remote login via XDMCP, etc. at the same time, the system becomes unstable and crashes: on the screen is only a colored noise visible and the system hangs completely. After reboot the text messages from the bios and from grub is displayed well, but when ubuntu 9.10 switches to graphics mode, there will appear blinking colored blocks (looks like a text mode?!) all over the monitor and the system hangs. I have to completely remove the power cord for a minute and then everything works fine again.
