https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D250248 --- Comment #13 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to Alexander Motin from comment #12) I believe that the problem with too early unsolicited notifications is that= dev can be not NULL but it is not attached yet (meaning that there are no driver methods). bus_generic_attach() is called after the codec discovery loop. So, an alternative solution could be for hdac_unsolq_flush() to check both = dev !=3D NULL and device_is_attached(dev). Still could be somewhat racy. Regarding the shutdown method -- yes, there is no need to detach HDA driver during shutdown. At the same time, there is no need to keep it attached too. So, I am ambivalent about that. --=20 You are receiving this mail because: You are the assignee for the bug.=
