https://bugzilla.kernel.org/show_bug.cgi?id=25192 --- Comment #6 from Adam Radford <aradford@xxxxxxxxx> 2010-12-19 17:49:10 --- No need to add prints to twa_probe(). In twa_poll_response(), just add this printk() and report the results: response_queue.value = readl(TW_RESPONSE_QUEUE_REG_ADDR(tw_dev)); printk(KERN_WARNING "3w-9xxx: response_queue.value = 0x%x, request_id = 0x%x\n", response_queue.value, request_id); response_request_id = TW_RESID_OUT(response_queue.response_id); if (request_id != response_request_id) { TW_PRINTK(tw_dev->host, TW_DRIVER, 0x1e, "Found unexpected request id while polling for response"); goto out; } We call twa_empty_response_queue() before this to junk garbage responses in the reigsters on power-up, so if we don't see anything even remotely close to the correct response in response_queue.value, that will tell us a lot. -Adam -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
