My IBM support team alerted me to an issue with C6 states for those processors when running Linux and the intel_idle kernel module is used. The IBM solutions page, http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=migr-5091901, recommends disabling intel_idle. I propose intel_idle disable C6 for the affected processors.

If so, you should probably request a firmware update from IBM. If that's not a possibility, and if it is necessary to disable package C6 in this situation, it'd be nice to determine what the BIOS workaround actually does and limit the quirk to that case. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
