Guru,
I installed Windows XP DDK on Windows 2000 computer and built the
sample code 1394Diag.sys under Win 2K free build environment. I tried to
use the 1394diag.sys as the device driver for my 1394 communication system
(a PCI 1394 card in the computer which is connected to an external
device).
I have two problems:
(1)If I power down the external device, I have blue screen with the error
code KNODE_EXCEPTION_NOT_HANDLED (1E C0000005…) from ntoskrnl.exe. I
think the problem is due to the surprise remove. But I do not know whether
it is the hardware problem or the device driver problem and how to fix it.
(2)In normal case, the user mode application runs fine to send data to or
receive data from the external device through the device driver. But, if I
turn on the Driver Verifier and enable all the Verification Type (I/O
verification with Level 2), the user mode application hungs up in 15mins
and I have to power down the computer and the external device in order to
clean the mess.
Do you have the similar problem with the 1394diag.sys? The 1394diag sample
code has been changed between the Windows 2000 and Windows XP.
Thanks in advance
Best Regards
Han
