Hi,
I applied the patch to a 2.6.20 kernel and tried the 2.6.21-rc4 and
still have the issue
The UML machine is in an infinite loop
ptrace(PTRACE_GETREGS, 16641, 0, 0x9dc5974) = 0
ptrace(PTRACE_GETFPXREGS, 16641, 0, 0x9dc5a24) = 0
ptrace(PTRACE_CONT, 16641, 0, SIGSEGV) = 0
waitpid(16641, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGUSR1}], WSTOPPED) =
16641
--- SIGCHLD (Child exited) @ 0 (0) ---
ptrace(PTRACE_SETREGS, 16641, 0, 0x9dc5974) = 0
ptrace(PTRACE_SETFPXREGS, 16641, 0, 0x9dc5a24) = 0
ptrace(0x1f /* PTRACE_??? */, 16641, 0, 0) = 0
--- SIGCHLD (Child exited) @ 0 (0) ---
waitpid(16641, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGSEGV}], WSTOPPED) =
16641
ptrace(PTRACE_GETREGS, 16641, 0, 0x9dc5974) = 0
ptrace(PTRACE_GETFPXREGS, 16641, 0, 0x9dc5a24) = 0
ptrace(PTRACE_CONT, 16641, 0, SIGSEGV) = 0
--- SIGCHLD (Child exited) @ 0 (0) ---
Do I have to change things on my host machine ? (I use 2.6.18-1.2798
with no skas3 patch)

Why are you insisting on a 2.6.18 UML?
I have tried many patches from the list and was not able to be successful
(hang after VFS: Mounted root (ext3 filesystem) readonly.)
Try 2.6.21-rc4 or this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=14251809b1921b1216568700f1be2f91a1cbb5c7
Does the host need a special patch to run recent UML kernel or is it
only an issue in the UML machine ?
It was a bug in UML's handing of newer host VDSOs.
