Created attachment 389050 [details] emerge --info for this dhcpcd My syslog adds these messages repeatedly after several minutes. It seems to be caused by IPv6 router advertisements and dhcpcd. I have upgraded dhcpcd and gcc to new versions, but the messages still occur. When I google "dhcpcd unaligned trap gentoo" the first result is Project:Alpha Porting Guide... My alpha acquires IPv6 and IPv4 addresses just fine. So dhcpcd is working. I suppose these messages are just a nuisance, but they still happen here. When they repeat, the address numbers are the same, so I'm just pasting in one set.

Hi Don Which dhcpcd version is this? There was an unaligned access error fixed on BeagleBone fairly recently and was included in dhcpcd-6.5.0. If your dhcpcd is older, please upgrade. If it's newer, can you enable core dumps and ensure dhcpcd is built with debugging symbols? http://wiki.gentoo.org/wiki//etc/portage/env http://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces#Core_dumps Then hopefully you can supply a backtrace so this can be fixed.

This was 6.4.3, the latest one marked stable. After some research, I figured out how to get version 6.6.1 from Gentoo. I don't see any unaligned trap messages now. Thank you. This seems to resolve my problem.
I am closing this since it is fixed in newer versions.
