From: gti4ever on 6 Jun 2010 04:58 Hi all, My UMDF driver crashes when it is being disabled or uninstalled. Using Windbg, I got the following error: ntdll!NtWaitForWorkViaWorkerFactory+0xa: 00000000`772317ba c3 ret When I used !analyze -v command, it only shows the following info: Last event: 13dc.12b4: Exit process 0:13dc, code 70000003 debugger time: Sun Jun 6 16:35:05.808 2010 (UTC + 8:00) Then I dump the thread info: .. 1 Id: 13dc.12b4 Suspend: -1 Teb: 000007ff`fffdc000 Unfrozen Start: ntdll!TppWorkerThread (00000000`771f8f00) Priority: 0 Priority class: 32 Affinity: 3 Here is the teb: TEB at 000007fffffdc000 ExceptionList: 0000000000000000 StackBase: 0000000000c00000 StackLimit: 0000000000bfe000 SubSystemTib: 0000000000000000 FiberData: 0000000000001e00 ArbitraryUserPointer: 0000000000000000 Self: 000007fffffdc000 EnvironmentPointer: 0000000000000000 ClientId: 00000000000013dc . 00000000000012b4 RpcHandle: 0000000000000000 Tls Storage: 000007fffffdc058 PEB Address: 000007fffffdb000 LastErrorValue: 0 LastStatusValue: c000000d Count Owned Locks: 0 HardErrorMode: 0 My question: 1. Where is this WaitForWorkViaWorkerFactory came from? Is it called by the framework? 2. How do I find which worker thread is calling this? I can only get the id of the thread (12b4, in this example), but I can't trace it back to any of my code. 3. What is code 70000003? 4. In TEB, the last status shows INVALID_PARAMETER. How do I find which function call got invalid parameter? Thanks for the help. G.
