I updated my um/include/asm/arch/termbits.h to match the standard 60 byte 
termios struct, and this fixed the kernel hang during boot.  However, it did 
not make the random failures on calls to tcsetattr go away.

The result is that I sometimes get the following during boot:

<snip>
NET4: Linux TCP/IP 1.0 for NET4.0
                                  IP Protocols: ICMP, UDP, TCP
IP: routing cache hash table of 512 buckets, 4Kbytes
<snip>

Instead of the correct output:

<snip>
NET4: Linux TCP/IP 1.0 for NET4.0
IP Protocols: ICMP, UDP, TCP
IP: routing cache hash table of 512 buckets, 4Kbytes
<snip>

Notice the indented "IP Protocols"?  That's where tcsetattr failed.
