Error messages booting 2.6.16-pre3
A message that is not in the archive (sent off-list or not yet received): [email protected]
So I finally got around to building 2.6.16-pre3 on my newly upgraded Ubuntu "Flatulent Badger" system, like so:
tar xvjf linux-2.6.13-rc3.tar.bz2
cat > allno.config << EOFCONFIG_MODE_SKAS=yCONFIG_BINFMT_ELF=yCONFIG_HOSTFS=yCONFIG_SYSCTL=yCONFIG_STDERR_CONSOLE=yCONFIG_UNIX98_PTYS=yCONFIG_BLK_DEV_LOOP=yCONFIG_LBD=yCONFIG_EXT2_FS=yCONFIG_PROC_FS=y
EOF
make ARCH=um allnoconfig
make ARCH=um
Run it:
./linux rootfstype=hostfs rw init=/bin/sh
And it's developed yet more verbose error messages:

Came up and ran, but looks really ugly. Entirely reproducible so far...
Anybody got any ideas?

I don't know about the rest of this, but something like this just happened to me. It was attaching the consoles to a host portal which another UML was already using. I got semi-reasonable "that portal is already in use" errors in between the parse_chan_pair things.
So, were you trying to reuse some host devices, and which ones? An improvement in the errors might be in order here.

I don't know. The did my standard "rootfstype=hostfs rw init=/bin/sh" thing, which should only have on process (a shell) on /dev/console. All that happened before that even managed to run /bin/sh.
I don't think I had any other type of console support even built into the thing. (Console on stderr support, everything else disabled.)
No idea what devices it was talking about...
