I don't see you coming forward with a solution beyond "let's revert the commit" or "let's comment out the lock" - neither of which are an option for mainline kernels. Until *you* do, since you obviously have better ideas, "we have no real option". But, as I've said, one of the *important* characteristics of serial console is that it is synchronous with the kernel, so it can be relied upon to get complete messages out if the kernel crashes after a printk() has been executed, and that must not be lost. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 10.2Mbps down 587kbps up
