Ok, understood. I got powernow-k8 working now but it took a hack. Basically, I downloaded the Feisty kernel source (2.6.20-16) and edited the powernow-k8.c file and commented out the lines: //if (num_online_cpus() != 1) { // printk(KERN_ERR PFX "MP systems not supported by PSB BIOS structure\n"); // kfree(data); // return -ENODEV; //} This allows the driver to get past this non-compliance and finish loading properly. This actually works even with empty "Processor" tables in the dsdt.
Here's my dmesg (first attempt at 16603 was with the original driver, second attempt at 17203 was with the modified driver): [16603.332000] powernow-k8: Found 2 AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ processors (version 2.00.00) [16603.332000] powernow-k8: MP systems not supported by PSB BIOS structure [16603.332000] powernow-k8: MP systems not supported by PSB BIOS structure [17203.268000] powernow-k8: Found 2 AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ processors (version 2.00.00) [17203.272000] powernow-k8: 0 : fid 0x2 (1000 MHz), vid 0x12 [17203.272000] powernow-k8: 1 : fid 0xa (1800 MHz), vid 0x10 [17203.272000] powernow-k8: 2 : fid 0xc (2000 MHz), vid 0xe [17203.272000] powernow-k8: 3 : fid 0xe (2200 MHz), vid 0xc [17203.272000] powernow-k8: 4 : fid 0x10 (2400 MHz), vid 0xa [17203.272000] powernow-k8: 5 : fid 0x11 (2500 MHz), vid 0x9 I attached my compiled powernow-k8 but use it at your own risk. ** Attachment added: "powernow-k8.ko" http://launchpadlibrarian.net/10060410/powernow-k8.ko -- Power states AMD64x2 broken https://bugs.launchpad.net/bugs/147762 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
