RaspberryPi 3B segfaults on 15.1-RELEASE

V

Running into an issue with segfaults ever since upgrading to 15.1 on a RPi3B (1GB RAM). Did not notice it before, but after upgrading it to 15.1, I did start seeing them afterwards. Been seeing messages like the following:

Code: 
koraga kernel: pid 9807 (pkg), jid 0, uid 0: exited on signal 11 (core dumped)
koraga kernel: pid 13163 (cron), jid 0, uid 0: exited on signal 11 (no core dump - sugid process denied by kern.sugid_coredump)

I have gotten them in processes including bash, cron, dhcpd, named, netstat, ntpd, pkg, ps, sudo, tmux, top, vi. All were standard pkg-installed packages. Now I am not a programmer, so I am not sure where to even begin to start looking. I know that signal 11 is generally something trying to access out of range memory, or it can also be a hardware problem. As I said, I noticed it happening more often since upgrading to 15.1.

Any suggestions on how to proceed?

Thanks,

This is due to a chip bug. There is a new libc.so.7 as part of patch 2 that should fix this. You can probably run freebsd-update on a different arm machine and use the -b option to target the sdcard for your pi3 (mounted on this other machine) but I haven't tried this before....

Thanks bakul! For the record, my system is on 15.1-p2. Here is the freebsd-version info and the sha256 sum of libc.so.7:

Code: 
[root@koraga ~]# freebsd-version -u
15.1-RELEASE-p2
[root@koraga ~]# sha256 /lib/libc.so.7
SHA256 (/lib/libc.so.7) = 8f14ca787dd853988f829aad291c7f4834a073d8398ceef0217433a07

Is this the right version? because i am getting several segfaults/signal 11s. I was running top in an ssh session to watch the freebsd-update (there were no updates to the system, btw), and top segfaulted on me.

And unfortunately, I do not have another pi...
