Huh! I managed to make it happen on Debian's 4.19.67
kernel. I had to redirect stdout/stderr to a file because printing to the
terminal slowed down the writes enough to prevent it from happening for me.
I guess it's hardware-dependent because I can't reproduce it on kernel
6.6 on a Raspberry Pi.

Unfortunately not; the older kernels failed to compile on my machine and
since I'm not a kernel developer and don't actually use any software that
relies on N_HDLC, I gave up... sorry.
