Hi all, Using a static bug finder (EBA - https://github.com/models-team/eba) I may have found a double spin_lock_irqsave in Linux 4.7's drivers/net/ethernet/ti/davinci_cpdma.c. The forward trace is as follows: 1. Starting un function `cpdma_clr_destroy' (defined in line 443); 2. the lock is taken first at 451: spin_lock_irqsave(&ctlr->lock, flags); 3. if (ctlr->state != CPDMA_STATE_IDLE) evaluates to `true' at 452; 4. we then call function `cpdma_ctlr_stop' passing `ctrl` to it, at 453; 6. finally, the lock is taken a second time at 346: spin_lock_irqsave(&ctlr->lock, flags); If that's a bug then I am willing to help with a patch. Thank you for your time, Iago
