Another report with the same symptoms, but this one with skas.  Has anyone
else seen this?

I am using a 2.6.6-1-k7 host kernel with the skas3 patch, but am 
having the same problem after upgrading to 2.4.26-2um-1:

I received this bug report from a Debian user.  It seems that something is
wrong with tt mode in 2.4.26-2um; I can reproduce a similar (though not
identical) hang by trying to boot with mode=tt (my host kernel is 2.6.6 with
skas3).  In my case, it hangs after init has started.  Booting in skas mode
works fine (which is why I didn't notice this in the first place).

Package: user-mode-linux
Version: 2.4.26-2um-1
Severity: normal


On upgrading user-mode-linux, my guest machines all hang during
startup, as below.

When I ran again with "|tee log.txt" to generate the log below, the
machine makes it through the kernel startup and hangs on usermode
daemons trying to start.

I'm not sure if I know enough to answer your question.  I normally
achieve a terminal with the below in inittab. I'm not running X, and
the only user mode linux tool I'm using besides the kernel itself is
the net daemon:

1:2345:respawn:/sbin/getty 38400 /dev/ttys/0


If it's helpful, I rolled back to the user-mode-linux version in
testing, and with that version, this is what follows the NET4 line in
the boot sequence:

IP: routing cache hash table of 2048 buckets, 16Kbytes
TCP: Hash tables configured (established 16384 bind 32768)
Linux IP multicast router 0.06 plus PIM-SM
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
kjournald starting.  Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
Mounted devfs on /dev
[followed by INIT and userland stuff]
