No. Is there a way to enable the kernel to give more
diagnostic debug output next time this error happens?

Is there a way to at least make the server reboot itself
next time the kernel is alerted to this problem before
crashing? When the server is rebooted, it works fine for
few more days before encountering this problem and
crashing again.
