Just a "me, too!" here. 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. Its more than a little irritating. -- -Steven In a time of universal deceit, telling the truth is a revolutionary act. -- George Orwell - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
