netwinder state?

[Valery Ushakov <uwe%stderr.spb.ru@localhost>]

TL;DR: Does anyone still have a netwinder and if so, does it boot 10
or current?


I tried to boot current on mine but it seems to choke.

Slighlty trimmed down GENERIC with serial console fails to load:

  Transferring block 8200 (4198400 bytes)<1>Unable to handle kernel paging request at virtual address c20041e0
  current->tss.memmap = 00008000

may be it's grown too big or something.

Trimming it down some more to

     text	    data     bss       dec	    hex	filename
  2820792	  601168   94952   3516912	 35a9f0 netbsd.serial

at least manages to get me to:

I have some old kernels in the old /tftpboot, and I can boot

  NetBSD 4.99.20 (SERIAL_FART) #7: Mon Jun 25 06:39:33 MSD 2007

to the root device prompt and I guess that

  NetBSD 9.99.10 (FART) #1: Thu Aug 22 04:29:59 MSK 2019

is also ok b/c I did previously boot it (old nfs server has its
dmesg.boot) and it loads ok, but then I can't see what it does b/c
it's a wscons kernel and I don't have a monitor hooked up, only
serial.

One difference I can spot is that my older kernles have 4 segments,
for start, text&c, data, and bss, but the new one has only 3, with
data and bss being merged in one.

I can't really do much testing as I don't yet have "lab" setup at the
new place and I forgot more or less everything about arm in general
and netwinder in particular.  So does anyone still have a netwinder in
storage and could do a bit of testing?
