Hi Alexander, we found a oops when tcpdump is used to write to a file on a USB stick and then unplugging the USB stick. this were tested and reproducible on every system that we had on hand, this includes different platforms (x86_64 / arm). uname -a of the systems: 4.14.142 #0 SMP PREEMPT Tue Aug 6 10:39:48 2019 aarch64 GNU/Linux 4.15.0-64-generic #73-Ubuntu SMP Thu Sep 12 13:16:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux 5.0.0-36-generic #39~18.04.1-Ubuntu SMP Tue Nov 12 11:09:50 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux steps to reproduce: - create FAT32 USB stick - mount USB stick - run "sudo tcpdump -w <USB stick path>/tcpdump.pcap" - unplug USB stick If more info is needed feel free to ask.
