I do think we care, but I don't think anybody in particular feels singled
out as a maintainer...

Ok, that's not exactly new then, which implies that not a *lot* of people
even care ;)

Do you think you'd be willing to try to figure out when it started? You
seem to be the first one to have even noticed.

(I tried to google it, and the most recent thing google finds is your
report, although I also saw a report of somebody trying it under qemu in
July last year and also reported a hang)

Looking through the history of the last few years (it in git), I don't see
anything even *remotely* suspicious there, so it's probably either
(a) really old, and hasn't worked in a loong time and nobody just uses it
(b) something really stupid that happened while doing other cleanups (but
the changes in the last two years are *literally* just things like
removing devfs support)
(c) some infrastructure change that subtly broke lpconsole, probably
causing an oops during printk, which obviously results in a printk
itself, which thus hangs.

It would be good to get it fixed, although for obvious reasons it's not a
huge priority..
