[uml-devel] ubd=mmap problem

["Sven 'Darkman' Michels" <sven@darkman.de>]

Hi there,

i started uml with udb=mmap, the box runs fine but today i
noticed that the box was terminated after a nightly cron
run inside the uml. While trying to figure out what the
problem was, i noticed that the uml can't reboot anymore
cause it hangs in an endless loop when unmounting the devices.
all i saw was:
map : /proc/mm map failed, err = 9
map : /proc/mm map failed, err = 9
map : /proc/mm map failed, err = 9
map : /proc/mm map failed, err = 9
map : /proc/mm map failed, err = 9
map : /proc/mm map failed, err = 9

this was with 2.4.23 and latest uml 2.4.22 patch. So i thought
its an problem with the patches and builded a fres 2.4.23 with
the latest -1 patch. But the problem is still there. When i
remove the udb=mmap from my startup line, uml works and reboots
like expected. Anyone had that too or can tell me what the
Problem is? ;) The host is running 2.4.22 with skas patch.

Regards,
Sven
