I was not intentionally changing the packets being sent.

Could you try to capture tcpdump, including contents of packet,
ideally in both working and broken sessions?

Could you try setting

-#define TIMEOUT                5000UL
+#define TIMEOUT                100UL

in net/tftp.c to something like 1000UL?

Thanks,
