Seems the crash is coming from bad locking
I have located exact place where the problem is manifested and
did this patch:
--- drivers/input/misc/uinput.c.orig 2005-10-15 10:09:38.000000000 +0200
+++ drivers/input/misc/uinput.c 2005-10-16 22:19:20.000000000 +0200
@@ -93,7 +93,8 @@ static void uinput_request_done(struct u
complete(&request->done);
/* Mark slot as available */
- udev->requests[request->id] = NULL;
+ if(request->id >= 0 && request->id < UINPUT_NUM_REQUESTS)
+ udev->requests[request->id] = NULL;
wake_up_interruptible(&udev->requests_waitq);
}
This checks wether request id has some sane value.
This way I have avoided crashes but now I'm running
of request[ ] slots, sometimes they tend to leak and
when all the slots are exhausted no more effects can
be accepted.
