I have bought another computer, not SN78SH7. I have tried a dedicated graphics card, but the system was still unstable and nearly unusable. I assume, that it was a hardware issue, because the system has shown some more courious behavior: after changing some bios settings, it hasn't reboot. I had to switch off the power to reboot.
When I switch the fan to manual speed and set it to maximum, the system became nearly stable. But after some months, the instability comes again, it seems that some dust has decreased to cooling power, so the system reaches again some thermal problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/495768 Title: System crashes at high CPU load Shuttle Barebone SN78SH7 with GeForce 8200 onboard graphic -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
