J'ai une machine virtuelle VMware exécutant Debian Wheezy. J'ai compilé mon propre kernel 3.14. J'ai remarqué dmesg
est inondé de messages pci BAR 7: can't assign io (size 0x1000)
.
Je n'ai aucune idée de ce que ces messages signifient. La VM semble fonctionner correctement, je ne vois aucun problème. Néanless, je suis dérangé par ces messages d'erreur, et je serais heureux si je pouvais me débarrasser d'eux.
Quelqu'un pourrait-il expliquer
1) que signifient ces messages
2) comment puis-je me débarrasser d'eux

En fait, dmesg contient plus de 550 lignes de journaux (de debugging) liés au PCI. J'ai collé la partie pertinente ici
Ils ne sont pas utiles et inondent mes journaux
Il me semble que vous rencontrez un bug lié à l'allocation de memory pour le débit des données du bus PCI, malgré le fait que vous exécutez dans une machine virtuelle. Bien que je ne sois pas familier avec VMWare, je soupçonne qu'il peut y avoir une émulation PCI ou un paramètre lié à l'allocation memory que vous pourriez modifier pour le réparer.
Le fil de discussion référencé à la fin de ce post suggère qu'un problème similaire pourrait être résolu en désactivant ACPI, bien que je ne puisse pas garantir l'exactitude de ce fil.
Je soupçonne (bien que je n'aie aucune information à l'appui, alors prenez-la avec un grain de sel) que cela peut avoir quelque chose à voir avec l'architecture que vous imitez. Si vous émulez 32 bits x86, je suggérerais peut-être d'essayer d'émuler la version 64 bits du même logiciel, et de tester si cela se produit là aussi.
En ce qui concerne la suppression du journal, je pense que cela peut facilement être fait en utilisant dmesg -C
, ou peut-être (si vous souhaitez l'automatiser) la mise en place d'une tâche cron pour exécuter la tâche ci-dessus toutes les heures.

Il est lié à l'allocation de memory pour le débit des données du bus PCI. Veuillez activer l'option Traffic Shaping dans vSwitch via vSphere Client.
J'ai essayé ceci et fonctionne bien pour moi.
