This was done in light of the fact that ttyS is apparently reserved for traditional PC-style serial controllers. I've spent the last day or two trying to bring my setup up to a 2.6.37 kernel. So far this has been quite painless, although I did get hung up on one simple issue resulting from this name change for several hours. Namely, the inittab still uses the ttyS naming, resulting in no visible login prompt to be started. This is in addition to changing the kernel's console= command line argument in the u-boot configuration. This sort of naming mismatch could be tricky to handle, since openembedded users will no doubt soon be using both pre- and post-2.6.37 kernels. Any clever ideas for how this could be dealt with in an non-obtrusive way? Cheers, - Ben
