It should reboot automatically. Unless you have enabled the
kernel debugger; in that case it enters the kernel debugger
and waits for commands.
Maybe the root cause for the panic also explains why the
system is unable to reset the machine and reboot automatically?
Did you try to save the panic crash dump and have a look
why exactly it is panicing?
The following should save the crash dump:
mkdir -p /var/crash/`hostname`/
savecore /var/crash/`hostname`/
To enable automatic saving of crash dumps at boot time, run
dumpadm -y
Run the mdb debugger on the unix.N + vmcore.N files
found in the /var/crash/`hostname`/ directory, e.g.
mdb -k /var/crash/opensolaris/unix.0 /var/crash/opensolaris/vmcore.0
Basic information about the crash can be found from within mdb
using these commands:
::status
::msgbuf
::stack
::cpuinfo -v
