@rostedt woo!

do the printk patches also affect non-rt kernels? i remember seeing some buffering solution or something in the past (and hey i wouldn't complain about faster boot times with 115200 baud - as long as it doesn't drop log messages on crash)

Yes it does affect non-RT kernels. Like all other RT features added to upstream, it improves vanilla Linux. The graphics developers wanted this change. It will allow for things like a blue screen of death where you can see an oops from a graphical interface.

@rostedt @cas It should be said that printk() now behaves differently. Previously you could cli(); printk(); while(1); and message would go out. Now you need to panic() or some kernel parameter, IIRC.
