Assertion failure in cmwrapr.c

NTDEV
1

Deva,

I’m using code based on Walter Oney’s example code as a framework for my
driver. I’m testing under the driver verifier on XP. During install of the
driver, I get the assertion failure:

ASSERT_PASSIVE_LEVEL failed … Irql = 1

*** Assertion failed: FALSE

*** Source File: D:\xpclient\base\ntos\config\cmwrapr.c line 297

I can ignore the error and get everything running, I just hesitate to ship
the driver without understanding what this is all about.

Thanks for any help! Hopefully it is OK for someone whose code causes
asserts to write kernel mode drivers… ;^)

Your in a function that expects to be at PASSIVE_LEVEL (0) but IRQL is at
APC_LEVEL (1).

Calling a registry function from APC_LEVEL.
