#541 reopened defect

Trap in krnl when PM initializes on Nvidea board in /VW mode

Reported by: yoda Owned by: David Azarewicz
Priority: critical Milestone: Release 4.00
Component: ACPI PSD Version: 3.21.04
Keywords: NVIDIA Cc:


ASUS A8N SLI Premium AMD 3800X2 NForce 4 chipset Award 6.0PG BIOS 3GB RAM.

It boots in all other modes.

From Wiki:

Some motherboards which use an NVIDIA chipset will generate spurious interrupts in Mode 1 (/VW mode) when the desktop starts. These interrupts occur in a way that cannot be handled by the kernel and cause a kernel trap. There currently is no solution to this problem. You cannot use the /VW switch on these motherboards.

This problem was fixed many years ago in in Pavels ACPI builds. First a switch was added "/DV:0x57" to use the fix. Later this was made default for all.

From DOCS: /DV:vector - Dummy Vector - hide the vector. The kernel will not

process it. (/DV:0x57 is enabled by default on every PC now)

Please get this fix back in.

Your information is incorrect. The problem has nothing to do with what you suggest. When I find a solution it will be implemented.

The ticket represents a trap in os2krnl in /VW mode, which is for real.

I see no reason to close a ticket for a real problem, as long as it exists.

I'd happily provide you with other information, just ask what you need.

It is a nasty habit to close tickets with real problems, when you haven't fixed them.

Comments like "This problem was fixed many years ago..." are not helpful, and in this case not true.

Statements like "Please get this fix back in" are not helpful and will not get you any support because it presumes that there was a fix (which is not true) and that it was taken out (also not true).

This problem only affects an optional mode of operation, not the normal mode of operation, and as such is a lower priority task.

If you want to be helpful, save me some time by helping me find the hardware data sheet for the NVIDIA chipset on that motherboard that includes all the registers and bit definitions.
