Ubuntu 9.10 should be ok with the applied patch, because kernels after 2.6.26 are nanokernels (ie, they have STA_NANO available). However, according to Debian maintainer Kurt Roeckx, using this patch on a non-nano kernel (eg Hardy) may have some odd side-effects. If people are backporting Karmic's ntp to Ubuntu 8.04 LTS, they should be aware of this issue.

An alternate patch that checks if the kernel supports nano seconds or not is at: /support. ntp.org/ bugs/show_ bug.cgi? id=888
