Package: src:linux Version: 4.15.11-1 Severity: normal Hi,
I found a regression in linux-image-4.15.0-2-armmp on Odroid XU4Q resulting in the kernel log below. Downgrading to 4.14.0-3-armmp doesn't show this behaviour, so I assume it's a regression. Also, restarting udev takes along time, maybe related. The Odroid works fine otherwise. I can reproduce this on two different Odroids and can try to bisect next weekend.
