Package: user-mode-linux
Version: 2.6.16-1um-2
Severity: normal


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.

I've tested this with a number of guest images; debian sid, ubuntu
breezy & dapper. Doesn't appear to be an NPTL issue; it crashes under
2.6.16 whether the /lib/tls libraries are present or not.


The boot messages when it fails:
