OK, if you really want that kernel, and if you do not want to just run it under KVM (which requires support from the host processor), or QEMU (hopelessly slow), it's a matter of how many patches you need. Uml has never been _that_ easily portable. But at the time, I packaged myself some bugfixes to UML, to run on slightly newer kernels, and while the website is down, I will send them to you in a private mail. If you don't know who I am, just look up 'Blaisorblade' on the Internet: I was UML co-maintainer. Since 2.4 kernels are relatively similar, you might want to try patchsets 2.4.28-bs2 or 2.4.32-bs3. They apply _more or less_ to any 2.4 kernel (more or less). I suggest you that first you try to get, say, a 2.4.28 kernel running (which might work with my patchset or might require a bit more work), and then backport to 2.4.24 the needed fixes (which should be easy enough). Or you might really want to boot it with an older host kernel. Say inside another non-UML virtual machine (if it works at all, I'm not that sure). Newer the host distro, more trouble you get. Those patches worked fine at the release date on the host 2.6 kernel I used, kind of the latest released, but we are talking about May 2006. Anyway, I'm going to send you the next mail (to avoid sending big attachments on-list), with both the packaged and splitout patches. Note: they already _include_ the 2.4.24-1 patch. > Also I downloaded nucleus called linux-wl-2.6 (it's compiled 2-4.24 for 2.6 > hosts) but my UML keeps crushing with > ============================================ > Checking for the skas3 patch in the host...not found > Checking for /proc/mm...not found > Kernel virtual memory size shrunk to 239075328 bytes > tracing thread pid = 20844 > Checking for /dev/anon on the host...Not available (open failed with errno > 2) > Checking for /dev/anon on the host...Not available (open failed with errno > 2) > Checking for /dev/anon on the host...Not available (open failed with errno > 2) > Checking for /dev/anon on the host...Not available (open failed with errno > 2) > Linux version 2.4.24-1um (vi...@pc-muskar.auto.ucl.ac.be) (gcc version 2.96 > 20000731 (Red Hat Linux 7.3 2.96-113)) #7 Fri Feb 4 17:01:08 GMT 2005 > On node 0 totalpages: 65536 > zone(0): 65536 pages. > zone(1): 0 pages. > zone(2): 0 pages. > Kernel command line: mem=256M umid=ordi0 > ubd0=cow0,../SysFich/root_fs_debian2.2_small root=/dev/ubd0 > Calibrating delay loop... 2516.58 BogoMIPS > Memory: 236344k available > Dentry cache hash table entries: 32768 (order: 6, 262144 bytes) > Inode cache hash table entries: 16384 (order: 5, 131072 bytes) > Mount cache hash table entries: 512 (order: 0, 4096 bytes) > Buffer cache hash table entries: 16384 (order: 4, 65536 bytes) > Page-cache hash table entries: 65536 (order: 6, 262144 bytes) > Checking for host processor cmov support...Yes > Checking for host processor xmm support...No > Checking that ptrace can change system call numbers...OK > Checking that host ptys support output SIGIO...Yes > Checking that host ptys support SIGIO on close...No, enabling workaround > POSIX conformance testing by UNIFIX > Linux NET4.0 for Linux 2.4 > Based upon Swansea University Computer Society NET3.039 > Initializing RT netlink socket > Starting kswapd > VFS: Disk quotas vdquot_6.5.1 > devfs: v1.12c (20020818) Richard Gooch (rgo...@atnf.csiro.au) > devfs: boot_options: 0x1 > JFFS version 1.0, (C) 1999, 2000 Axis Communications AB > JFFS2 version 2.1.

Anyway, start from 2.4.28-bs2, really. I do recommend you that. (And never try with anything like 2.4.24-2um onwards from Jeff website. They were much more unstable because of the introduction of humfs, and I took any good patch from those kernels).
