Hello UML developers,
I received the following bugreport for 2.6.16 UML running on a 2.6.16
host (both are debian packages). I found a similar report on a french
site[1], it seems to be the same problem.
Can you help putting some light there?
Thanks in advance

I also get a problem specific to host 2.6.16 kernels, but that's when I run
x64 guests on x64 2.6.16 hosts (x86 32-bit guests work normally); I've not
tested 32-bit 2.6.16 hosts.
The error message is different. However, I can't exclude there is the same
root cause acting in a different way, but I've now debugged this a bit and
this seems unlikely.

When user-mode linux is used with a host kernel of
linux-image-2.6.16-1-k7 (ie, the package in sid), it panics. When the
host kernel is linux-image-2.6.15-1-k7 (also from sid), it works
perfectly.
