I've seen some symptoms very similar to this with the same kernel version. When I try to run a getty a tty which is also the console (not sure what happens if it isn't a console) it freezes up and doesn't respond or echo kernels. Works on 2.4.2, just like yours. >From an strace of getty, it appears to be hanging in ioctl(..., TCSETSW I hope this gets resolved.
