Hi, Adding relevant people to CC. > Original bug report: https://bugs.archlinux.org/task/62391 Thanks for the report! > May be related to this email: https://lkml.org/lkml/2019/4/4/518, > unconfirmed. Yes, that's the one. Hans, there are two problems with the dev_err here. One: It is not ratelimited. Two: We don't see which driver tried to transfer something with a suspended adapter. My suggestion: Use dev_WARN_ONCE(). And it seems we should think again about ratelimiting in the core, too. > As the related hardware is quite specific, my question is more about > limiting the ammount of output the i2c_designware module produces when > encounters such errors. Valid request. If we decide to move to dev_WARN_*, then I'd like to ask you to run the fix again because behind all this, there is another driver which needs fixing, and the WARN will point to it hopefully. Thanks, Wolfram
