53.36 Linux graphics driver freezes system when hyperthreading is enabled on Linux2.6
I'm running Linux 2.6.1 on an Abit IS7 motherboard and a Pentium 4 2,8GHz HyperThreading processor. When switching from the X Window System to the text console the system freezes if the NVidia 53.36 graphics driver is being used and HyperThreading is in use.

It will not freeze if ACPI is off and thus HyperThreading is disabled. The 46.20 driver with Linux 2.6 patch from www.minion.de does not have this problem but 53.28 driver did. I'm not using the framebuffer console but the normal text console. I tried enabling the FB console though but it didn't help. Also using acpi=ht did not help - if HT is enabled (or the system sees two CPUs) the system will freeze when switching from X to the console.

Is there any way around this other than disabling HT/SMP or downgrading to 46.20?

It seems it is not an ACPI problem. At least I tried everything mentioned on that page (fixed a couple of ACPI compiler warnings but they were not relevant anyway) but it still freezes. There were some checks for Windows in the ACPI but changing the OS name didn't help either.

The graphics card is a GeForce FX 5200 card from XFX, btw.

Still freezing with Linux 2.6.2.
