I have switched my network from WPA2 AES to WPA1 TKIP, and managed to run the machine for a much longer period before the lock-up. Now it locked up -- and for the first time, not completely dead, but with the leftmost LED above the keyboard flashing! Is it possible to obtain debug information while in this state?

Yes, it provides both -mfix-loongson2f-nop and -mfix-loongson2f-jump. To be clear - I only built the .37 and .38 kernels (not .32), used them briefly, and since I discovered they make no difference with regard to lock-ups, I switched back to using the prebuilt .38 kernel from linux-libre for now. -- With respect, Roman
