Package: src:linux
Version: 4.5-1~exp1
Severity: normal
Thanks for enabling support for raspberry pi 2!
It works for the most part, but floods syslog with messages:
[501966.870273] net_ratelimit: 35702 callbacks suppressed
[501966.875438] smsc95xx 1-1.1:1.0 eth0: kevent 2 may have been dropped
It seems to function ok, though I'm not sure if there's degraded
network performance...
Not sure if the version of the boot firmware and/or u-boot would likely
impact this, or running stretch/sid vs. jessie.
I also experience this on a second rpi2, similarly configured.
live well,
vagrant
