https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204298 --- Comment #3 from Alexander Motin <mav@FreeBSD.org> --- I like your idea of giving timeout a reference. I've even reworked your patch in IMO cleaner way (see new attachment). Unfortunately after doing that I hit the problem affecting both mine and your patches: device reference counters are protected by bus lock, that can not be acquired while holding device queue lock. I am not ready to say this approach is hopeless, but requires some more thinking. -- You are receiving this mail because: You are the assignee for the bug.
