Can't capture packets with tcpdump or dumpcap/tshark. Sigsev (Linode)

I'm running arch linux on my linode, everything is up to date in pacman. Whenever I try to run tcpdump or tshark it just gives me "Segmentation Fault". I checked the packages repo site and saw someone having the same issue and the fix was creating the /dev/bus/usb/001/001 which didn't fix the issue for me (still segfaults). When setting up the char device it uses the major version 189 which is usb_device on my linode /proc/devices doesn't show a usb_device anywhere.

So is there something I need to install or something I'm missing? In the past tcpdump has worked with no issues.

Thanks for reading, hope you can help.

You might want to try running it with gdb and do a backtrace after it segfaults to see what's causing that.

Already put a ticket in the trac with the gdb backtrace. Thanks tho. A mod can close this if needed.
