Hi John Baldwin:
Thank you for your reply!
Yes,I use an interrupt handler in my driver module and use a filter function. In the filter function,I call the __zt_transmit_chunk function which defined in the zaptel module(name zaptel.ko).

Do you use any interrupt handlers? If so, are you using a filter function?
Also, you can use the 'tid' command in kgdb to switch to a thread via a tid to
avoid having to search for a 'tid' in info threads.
