These issues have been lingering forever..
They do get posted on the list. Here are samples:
https://lore.kernel.org/netdev/676d25b2.050a0220.2f3838.0464.GAE@google.com/#r
https://lore.kernel.org/netdev/67d2a576.050a0220.14e108.0030.GAE@google.com/
https://lore.kernel.org/netdev/67946a0c.050a0220.3ab881.0010.GAE@google.com/
https://lore.kernel.org/netdev/66e96979.050a0220.252d9a.000a.GAE@google.com/
https://lore.kernel.org/netdev/6777334a.050a0220.3a8527.0058.GAE@google.com/#t

They all point to the same bisected commit, but am not sure whether
they are the same issue

To get you on Cc from syzbot - i think we'll have to add you as a
maintainer for taprio if you'd be okk with that..

cheers,
