During boot, if the level 14 timer limit is not set then the Solaris kernel panics with a division by zero error. Fix this by setting it to the default value as documented in obio.h. Also if the level 10 timer is not set with a limit of 0, the Solaris kernel constantly outputs "spurious interrupt at processor level 10" messages during boot.
