>Description:
the 7.0 release netbsd kernel boots on a BeagleBoneBlack but then resets (with no message) after about 50 seconds (measured from start of boot).
>How-To-Repeat:
Just boot kernel on BBB.  It's easiest to NFS boot a kernel using BBB's uboot:

    # setenv ipaddr 192.168.1.59
    # setenv serverip 192.168.1.4
    # tftpboot 82000000 netbsd.gz.ub
    # bootm

start timer (t = 0 sec).

When prompted for a root device, enter cpsw0 to boot with nfsroot, or enter ddb and poke around for a few seconds.  In either case BBB reboots without warning at t=50 seconds.
>Fix:
Unknown.

 Which watchdog devices show up in dmesg?

 You can check with

   wdogctl

 at the shell prompt.

 Can you please try:

 	wdogctl -u omapwdt32k0

 at the shell prompt and then wait 50 seconds?

 No, just a test to verify that it is actually the firing watchdog
 that kills it.

 Fix should be in the kernel driver to disarm the chip at attach time,
 or switch it to kernel tick mode.

 As a simple workaround, you can add it to rc.conf, like:

 	wdogctl=YES wdogctl_flags="-u omapwdt32k0"
