Моя цель — получить возможность использовать зонды пользовательского пространства на хосте Ubuntu 12.04/precise. Это возможно начиная с ядра 3.5.0, поэтому я установил следующие пакеты:
linux-headers-3.5.0-34
linux-headers-3.5.0-34-generic
linux-image-3.5.0-34-generic
linux-image-3.5.0-34-generic-dbgsym
linux-image-generic-lts-quantal
linux-source
linux-source-3.5.0
и systemtap v1.7 из 12.10/Quantal.
Но единственное, что я вижу после запуска любого stap-скрипта, это:
ERROR: module version mismatch (#55-Ubuntu SMP Thu Jun 6 20:18:19 UTC 2013 vs #55~precise1-Ubuntu SMP Fri Jun 7 16:25:50 UTC 2013), release 3.5.0-34-generic

systemtap v2.1 от 13.04/raring показывает точно такую же ошибку.
systemtap v1.6 (версия по умолчанию в 12.04) дает сбой во время компиляции:

К сожалению, обновление до 12.10/13.04 невозможно.
Итак, есть ли шанс получить рабочий systemtap с ядрами 3.5.0 или 3.8.0 в Ubuntu 12.04/precise?
