Seems to be a problem with calling the 64-bit overlay interface via ioctl from 32-bit userspace application. I rebuilt the symbol overlay utility for arm64, that fixes the ioctl issues in the overlay. Currently figuring out how to best to get arm64 packages distributed.

One more hint.

Here is the log level after I reboot. root@pi33:/home/mark# cat /proc/sys/kernel/printk 3 4 1 3

I am log in through wifi and ssh.

Now holding the berry button for the second I get:

root@pi33:/home/mark# Message from syslogd@pi33 at Apr 24 21:09:13 ... kernel:[ 2162.866783] Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP

Message from syslogd@pi33 at Apr 24 21:09:13 ... kernel:[ 2162.953113] Code: cb01000e b4fffc2e eb0201df 540004a3 (a940342c)

Now when I look at the log level, I get.

root@pi33:/home/mark# cat /proc/sys/kernel/printk 15 4 1 3

It sets the log level to 15 so from that point on I get messages on the display until I set the log level back down.

I have added 64-bit arm64 builds of all the Beepy packages to the PPA repo. This fixes the symbol overlay crash we were seeing when holding Berry on 64-bit. You will probably need to purge the 32-bit armhf packages first, then install the arm64 versions.
