MULTIPLE_IRP_REQUESTS_COMPLETED

NTDEV
1

I get this “Blue Screen” error sometimes and the computer shuts down.

I have written a serial port driver and installed the same. I am also
running a daemon (application) that reads data from this serial port
device thru the driver.

I get this error once in a while.
Any clue as to why this may be happenning ?

What exactly does “MULTIPLR_IRP_REQUESTS_COMPLETED” mean ?

Thanx
Kiran

Surprisingly enough, MULTIPLR_IRP_REQUESTS_COMPLETED means that your driver
managed to either complete the same IRP instance more than once, or convince
some other driver or the IO manager to provide the second and offending
completion. Your driver is at fault. Go here:
http://www.microsoft.com/whdc/hwdev/driver/kb-drv.mspx and read Q320275 and
Q326315 and Q191813. Run driver verifier against your driver. It is
generally very good at spotting these sorts of plumbing errors.

Mismatched IoMarkIrpPending and STATUS_PENDING return is the most probably
cause.
