The following devlink command on a 2700 triggers a panic every time.
Kernel is net-next at 26873308b21654b6e0785b9f9e2c5414d37a4c4c
$ devlink dpipe table dump pci/0000:03:00.0 name mlxsw_adj
devlink answers: No buffer space available
<hang>
I have seen several different stack traces and varying amounts of EMAD
errors on console:
[ 77.453364] mlxsw_spectrum 0000:03:00.0: EMAD reg access failed
(tid=64c24a400003688,reg_id=200b(sfn),type=query,status=0(operation
performed))
[ 77.466568] mlxsw_spectrum 0000:03:00.0: Failed to get FDB notifications
If it does not reproduce for you let me know and I'll grab a trace.
