What I typically do is route everything to 8250 early console and rip out everything printk buffer nonsense. That gets you a fairly reliable console, no locking, only vscnprintf() and OUTB banging. No printk() wanting to do wakeups and other such nonsense that doesn't work. I appreciate that might not be for everybody, but it also shouldn't be this hard to get something reliable. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
