That's also my experince: I'm currently running Linux 2.4.26 with UML patch 2.4.24-1 on a production system (kernel 2.6 with SKAS patch on the host) without major problems. When I used UML patch 2.4.24-2 or higher the guest systems were very unstable and crashed after a few hours. The linux processes on the host were simply killed by a segmentation fault or I got one of these error messages: Kernel panic: Segfault with no mm Kernel panic: switch_mm_skas - PTRACE_SWITCH_MM failed, errno = 0 I even tried to build a UML kernel on woody (where the AIO glibc headers are not available, so the kernel is built with gcc 2.95 and without AIO support) but the resulting kernel also was not very stable. So I suggest to use kernel 2.4.26 (or higher, when available) with UML patch 2.4.24-1 for the user-mode-linux Debian package (which is also used by some commercial hosting services like Linode). BTW, thanks for packaging!
