Bugcheck when running the Driver Verifier

Postby jla » Mon Feb 02, 2009 10:42 am

Hello. I'm part of a company that uses your device extensively for a significant part of our customers; lately we have experienced some stability problems (computers freezing at seemingly random frequency, impossible to reproduce "in lab").

While investigating this, my first culprit was obviously a faulty driver, so I activated the Driver Verifier. I found out that whenever I call UUIRTTransmitIR, the Verifier raises a bugcheck, code 0xc9 (DRIVER_VERIFIER_IOMANAGER_VIOLATION) with param #1 being 7 ("The driver called IoCompleteRequest while its cancel routine was still set.").

Of course, I can't say right now if this is the cause for the root problem (freezes) but even if it isn't, it's obviously preventing me from investigating further :)

Did anyone else had this kind of problems ? We're running XP Pro SP2, fully patched, with Intel Core2 Quad CPUs.

TIA
jla
