Ursache
Баг PowerPath.
Під час VPLEX-NDU директор VPLEX зависав через кілька секунд після початку. Це виявило баг у PowerPath, пов'язаний із відкриттям пристроїв, через що PowerPath випустив додатковий реліз. Цей додатковий реліз призводить до стану використання після безкоштовного використання та паніки щодо ядра Linux.

Lösung
PowerPath 6.1 HF1 та майбутні версії PowerPath мають виправлення цієї помилки.
Weitere Informationen
І Red Hat, і PowerPath Engineering змогли відтворити стан у лабораторії незалежно від VPLEX-NDU. Окрім зворотного сліду клієнта, було видно кілька різних панічних зворотних слідів.
Через особливості використання після безкоштовного використання справжня паніка помітна в кількох місцях.
