Hi there, I've been trying to run UML on FC6 (kernel 2.6.20-1.2933.fc6) and appear to have encountered the same issue as described in the following threads: http://www.mail-archive.com/use...@li.../ msg04571.html http://www.mail-archive.com/use...@li.../m sg04479.html Has there been any further resolution of trying to get UML to run on FC6? The system hangs when I get to "VFS: Mounted root (ext3 filesystem) readonly." I have applied patches described in both threads to kernel 2.6.19 and rebuilt and still encounter issues. I have also tried pre-built kernels 2.6.21.1 downloaded via http://uml.nagafix.co.uk/, and 2.6.13.4-bs5, 2.6.16.9-bs2, 2.6.18.1-bb2 from http://www.user-mode-linux.org/~blaisorblade/binaries/ I have attempted loads of prebuilt rootfs Busybox 1.5.0, 1.1.0, Debian 4.0 from http://uml.nagafix.co.uk/, and also a hostfs rootfs with most of the kernels.=20 I am able to get pre-built kernel and rootfs operating on Mepis (using kernel 2.6.18.1-bb2 and rootfs busybox-1.5.0) or Red Hat 7.3 (using kernel 2.4.32-bs3 and rootfs busybox-1.1.1) My command line has been something like ./linux rootfstype=3Dhostfs init=3D/bin/sh or=20 ./linux ubd0=3D./rootfs init=3D/bin/sh I have also various other switches described in http://uml.nagafix.co.uk/ and http://www.landley.net/code/UML.html Can anyone help?=20 Kind Regards Andrew Sinclair > Antoine Martin wrote: >>> Downgrading to skas-v8.2 makes things work fine again. >> Ah, did you get around to generate a v8.2 patch for 2.6.19? > > http://www.theshore.net/~caker/uml/patches/skas-2.6.19.1-v8.2.patch > > So far so good.

Do you know why exactly the kernel needs to be upgraded? Just curious.
