When i compile the gentoo-dev-sources with speedstep-centrino enabled and want to modprobe the module i only get that device is not recognized. Reproducible: Always Steps to Reproduce: 1. 2. 3. Actual Results: insert the patch from http://www.ussg.iu.edu/hypermail/linux/kernel/0408.0/1533.html
Created attachment 39747 [details, diff] the patch posted in the kernel mailinglist wont work in its original state
I've emailed the individual responsible for speedstep-centrino support in the kernel and he told me that there are issues with different Dothan models having different freq/voltage tables. He said that it is currently impossible to tell which one to use. I have a b0 Dothan 1.6GHz CPU and I got cpufreq support working by taking the speedstep-centrino driver from the 2.6.9 kernel (which introduces support for the newer Dothan variants), patching it with the patch you posted, then inserting it into my current kernel (2.6.8) and disabling ACPI table support (it won't compile with this enabled). I'm sure this is either risky or will fail for most people, but it at least means a solution may be in the near future.
can you perhaps post a patch for the actual version of the gentoo-dev-sources?
Sorry, I'm not going to patch this into gentoo-dev-sources. The only fixes we typically accept are ones from upstream -rc versions, but there are simply too many changes to speedstep-centrino in 2.6.9-rc for me to worry about. In the meantime, you may wish to test 2.6.9-rc2 to ensure that the driver works in that kernel, so that when gentoo-dev-sources-2.6.9 comes around, you don't have this problem. Thanks
