Len, can you remove this part of the dmi entry then: + { + .ident = "ThinkPad ", /* T40, T40p, T41, T41p, T42, T42p + R50, R50p */ + .matches = { + DMI_MATCH(DMI_BIOS_VENDOR, "IBM"), + DMI_MATCH(DMI_BIOS_VERSION, "1RET")}, + }, The others (these BIOSes seem to not be shared between that many machines) were tested that this patchset fixes sever bugs: - system freeze when using C-states on R40e - much faster booting on R50e Thanks, Thomas -- 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
