RE: [uml-devel] patch not applied cleanly (was Kernel panic on UML boot up)

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Thanks....I did search the archives for my original problem, which was UML
kernel panic on RH 9.0. The root
cause was RH 9.0 kernel mods triggering a bug in UML, if I remember right.
2-4-20-um patch was a suggested
Remedy for this problem, which I naturally assumed to be for the 2.4.20
kernel in RH 9.0, not the vanilla version. 

So here's my question : is there a clean patch to fix kernel panic (outer
trampolines error) on RH 9.0
runnng 2.4.20-8 kernel that comes with the distro?

Thanks,
Mittal
