Hiya,

I have UML 2.6.4-1 on a stock SuSE 8.1 box (also tried on 8.1) running 
2.4.19

The system boots fine an dnetworking comes up and works. The system
starts sshd, apache etc however, when the system starts bind9 the
UML kernel panics. This only happens when networking has not been 
brought up,
with networking started named starts fine.

Kernel panic: Kernel mode fault at addr 0x4, ip 0xa0030643

I can supply a disk image and kernel if required.

Thanks,

I'm getting a UML kernel panic whenever I run the j2eesdk (Java with EJB -
http://java.sun.com/j2ee/1.4/download.html#sdk) installer.  The panic is 
"Segfault with no mm".

I tried running the latest supported version (2.4.24-2), and I got several
backtraces of the crash:
http://sco.tuxrocks.com/uml/trace5.txt
http://sco.tuxrocks.com/uml/trace6.txt
http://sco.tuxrocks.com/uml/trace7.txt

The config file is at http://sco.tuxrocks.com/uml/config

Any ideas or suggestions?  Any help would be greatly appreciated.

Thanks,

Frank
