Joe,
Between next-20121022 and next-20121023, the serial console (on the ARM SoC Tegra at least) stopped working. The issue bisects down to this commit. I haven't had a chance to investigate why yet, I just finished bisected.
earlyprintk over the same UART works. Once the system has booted, a few late kernel messages do appear, and then getty/login over the UART works. So, it's just the printk messages that disappeared.
In case it's relevant, my command-line is:
console=ttyS0,115200n8 loglevel=8 rootwait rw earlyprintk root=PARTUUID=b2f82cda-2535-4779-b467-094a210fbae7
I'll continue to investigate further tomorrow, but just wanted to give you a heads-up in case you could immediately see anything obvious in the code.
