Yes it froze the system on iteration 3000

A C program without ioctl also froze it on iteration 887. Doing ioctl seems to
trigger it much faster at iteration ~200.

I ordered a USB-to-ethernet adapter in the meantime to try to get more
diagnostics through netconsole, instead of serial cable, will that work?

Or do you have enough information about what may be wrong so that I can cancel
the USB adapter order? Otherwise, it will arrive in 4-5 days. (USB-to-Ethernet
because I don't have a laptop with RJ-45 from my PC.)
