I have a problem whereby the nvidia drivers cause my system to hang/reboot a few seconds after startx. I have discovered that disabling the SMP/apic lines in the kernel fixes the problem. This occurs on 5.2-CURRENT and 4.9-RELEASE.
I first noticed this problem after a motherboard swap. The old motherboard was a Tyan Tiger MP and it was running 5.1-CURRENT at the time and nvidia drivers were working fine with SMP kernel. The motherboard died so I replaced it with a MSI K7D Master-L (MPX chipset). After that the nvidia drivers stopped working if SMP kernel enabled. I have tried NO_MIXED_MODE, disabling acpi and a lot of other BIOS options but no luck. I don't know if this is an nvidia driver issue or a problem with this particular motherboard/chipset. Any help appreciated. Thanks.
