I've just tried the linux-2.6.16 binary UML kernel from the new web
site, together with a guest ubuntu installation. Looks good at a first
glance, but I've hit several problems:

1) I mount /home with hostfs using the following line in fstab:
   none /home hostfs /home,rw 0 0

df shows:

none                 10413255443693385415481253412470784 
10413248933519167673017998136836096 47190722440083771496586606219886592  19% 
/home

2) the guest OS sees stale file content on hostfs mounts. E.g. I open a
   file in the UML machine, look at it, close it, edit on the host, open
   it again on the UML -- and I don't get the changes saved on the
   host. This is a major problem.

3) what do these messages mean:

setitimer: mpr (pid = 1646) provided invalid timeval it_value: tv_sec = 0 
tv_usec = 1790000
setitimer: mpr (pid = 1646) provided invalid timeval it_value: tv_sec = 0 
tv_usec = 1943000

... and do they have anything to do with:

4) my application sometimes hangs completely, eating CPU, until I type
   something in another console (!!!).

This is using the web-site-supplied 2.6.16 binary kernel, the host
machine is a 2.6.15.6 with skas3 applied, running Gentoo.
