btw. this only happens on linux-next (tested with next-20200522), not
on
5.7-rc7 (which has the same two patches of yours)
I wouldn't be surprised if the difference is due to
fw_devlink_pause/resume() calls in driver/of/property.c. It chops off
~1s in boot time by changing the order in which device links are
created from DT. So, I think it's just masking the issue.
On linux-next where you see the issue, can you get the logs with this
change:
+++ b/drivers/base/core.c
@@ -907,7 +907,10 @@ void device_links_driver_bound(struct device *dev)
*/
device_link_drop_managed(link);
} else {
- WARN_ON(link->status !=
DL_STATE_CONSUMER_PROBE);
+ WARN(link->status != DL_STATE_CONSUMER_PROBE,
+ "sup:%s - con:%s f:%d s:%d\n",
+ dev_name(supplier),
dev_name(link->consumer),
+ link->flags, link->status);
WRITE_ONCE(link->status, DL_STATE_ACTIVE);
}
My goal is to figure out the order in which the device links between
the supplier and consumers devices are created and how that's changing
the flag and status. Then I can come up with a fix.
Here we go (hopefully, my mail client won't screw up the line wrapping):
