Copia collegamentoCollegamento copiato negli appunti!
Updated cpuspeed packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The cpuspeed packages contain a daemon that dynamically changes the speed of processors depending upon their current workload. This package also allows users to enable CPU frequency scaling using in-kernel CPUfreq governors on Intel Centrino and AMD Athlon64/Opteron platforms.
Bug Fix
- BZ#1078211
- Previously, certain AMD processors were not entirely compatible with the CPU frequency scaling. As a consequence, a kernel panic could occur on some AMD-based Hardware Virtual Machine (HVM) guests when CPU frequency scaling was enabled. With this patch, the default CPU governor value has been set to "performance", which prevents this problem. Thus, unless the user changes the CPU governor setting, the kernel now no longer panics when CPU frequency scaling is enabled on HVM guests.
Users of cpuspeed are advised to upgrade to these updated packages, which fix this bug.
