        src/sys/kern: kern_subr.c

Log Message:
Run shutdown hooks whether or not the kernel has panicked.  Restores
NetBSD's shutdown behavior of more than 6 years before rev 1.176.
Ok joerg@.

It is essential that we restore some hardware to initial conditions
before rebooting, in order to avoid interfering with the BIOS
bootstrap.  For example, if NetBSD gives control back to the Soekris
comBIOS while the kernel text is write-protected, the BIOS bootstrap
hangs during the power-on self-test, "POST: 0123456789bcefghip".
In principle, bus masters can also interfere with BIOS boot.
