Hi,
I've a strange problem with ejabberd(a jabber server written in Erlang)
running under the user mode linux kernel. Almost everything works as
expected but a certain function, pubsub/pep, doesn't work. When I run
the very same installation in a chroot environment on the host, it
behaves correctl
Hi,
to the debian lenny kernels greater than 2.6.26-21 a patch has been
applied that causes hunks in sys_ia32.c, sys_i386_32.c and sys_x86_64.c.
This patchset is called untangle-the-do_mremap-mess. Exists a skas3 patch
that works with that kernels?
Regards,
Matthias

Hi,
I tried the kernel 2.6.33 and I still have the data corruption problems.
When I remount the partition with the sync option and repeat the test,
all files seem to be intact. I'm using an ext3 filesystem on a lvm
volume for my UMLs.

Hi,
it seems that there is a change between the debian patched kernels
2.6.26-21lenny2 and 2.6.26-21lenny3 which introduces (patch) problems
with the skas3 patch. It's not obvious for me to adjust the patch. I've
attached the original files and the rejects. Maybe someone can help.

Hi,
it's quite easy to halt my user-mode-linuxes with heavy io operation like
hashing big files. I'm not sure of I setup something wrong or this
behaviour can't be changed.
My host system is debian etch, default kernel with skas patch:
2.6.18-6-vserver+skas-k7
Guest systems are debian etch,
