BSOD with Hperthreading enabled

Hi Everyone,

In our product, we have application,Api and device driver.

When running in Windows XP with hyperthreading enabled i am getting BSOD with bugcheck id 0x000000C6, mentioning crash in ntoskrnl.exe when i am debugging with softice debugger.

This is not happening when i disable Hyperthreading...

I tested application without calling any of my device driver function calls...still it gives BSOD with the same bugcheck id....

Can anyone give me a good solution for this..

Thanks in advance

BSOD with hyperthreading enabled

Hi,
Sorry Mr.rsinfo and Mr.Arie for misunderstanding the question.
I found the reason for the BSOD in my application.This is not due to device driver.

My application is an multithreaded application,in which we send commands to the device connected through COM port.

In code, in a while loop WriteFile( ) is used to write to COM port which is opened already, without setting any timeouts.

Writing in COM port in while loop causing BSOD with 0x000000C6 bug id only when Hyperthreading enabled.....

Same code run without BSOD when Hyperthreading is disabled...

Can anyone give me the reason for this...I couldnt find the core cause with respect to Hyperthreading.

Thanks in advance
