http://www.linux-mips.org/archives/linux-mips/2006-02/msg00241.html is one example we just had on MIPS. On SGI IP22, using the serial console, you'd get the following on shutdown:
The system is going down for reboot NOW! INIT: Sending processes the TERM signal INIT: Sending proces
and then nothing at all. I'd never have suspected the serial driver, had not users reported that the machine shutdowns properly when using the framebuffer.
For the record, I don't mind whether it's BUG_ON or WARN_ON, but I just wanted to give this as an example of an "oops in hard-to-guess, place". -- Martin Michlmayr tbm@cyrius.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
