What it is doing is reporting bogus P-States to the OS. Good: Package (0x06) { 0x03E8, 0x00009C40, 0x64, 0x09, 0xE8202C82, 0x0482 }, Bogus: Package (0x06) { 0xFFFF, 0xFFFFFFFF, 0xFF, 0xFF, 0xFFFFFFFF, 0x03FF }, The driver is then doing the right thing and comparing the frequency (1st member) with the computed frequency from the control field (4th member) and reporting that they don't match and thus throwing away the bogus p-state. Reading your DSDT (and confirmed in your kernel log) you should still get two valid and working P-States, 2GHz and 1GHz. Do these work fine? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I had been reporting this problem because the message came up first after some online update, and I thought there's something wrong (which after all actually is, but not what I had thought). Changing bug summary to reflect this.
