>Description:
I activated the following probes in a proprietary userland application:
dtrace -p 45412 -n 'pid$target:foo::entry { ustack();}'
The following got spammed to the console:
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
kernel trap 12 with interrupts disabled
Incredibly, the kernel did not panic. When I stopped dtrace the messages
stopped and everything continued normally...
