Lockup issue with NetBSD 7


I just upgraded a PowerMac 9600 from NetBSD 5 to NetBSD 7 (netbsd-7 from 11-November-2015) and so far I've had two lockups. The first time I didn't have anything plugged in to the serial port. Plugging in a cable to try to see what was wrong before rebooting gave a spontaneous reboot. I left the serial cable installed, just in case, and when the second lockup happened it was unresponsive. Sending a break to get to ddb caused an immediate reboot. No crash dump ever occurred.

Here's the reboot when sending a break after lockup:

~Stopped in pid 0.2 (system) at  netbsd:zstty_stint+0x1b8:       b       netbsd:z

Is anyone else having lockup or ddb issues with NetBSD 7?
