First, it's good to see that the synaptics-patches from -mm made it into the mainstream kernel, they are necessary to make the synaptics work together with XFree here. However, there is a problem with ACPI: /proc/acpi/processor/CPU0/performance, which was there in previous versions of the kernel and allowed me to slow the CPU down in order to save power, disappeared in Linux 2.6.1-rc1. It's simply not there anymore. Was it replaced? If so, what is the right way to do it by now? Secondly, there also is a framebuffer related problem. I have VesaFB in kern and pass 'vga=791' to it at boot time. However, at the time when it switched to FB in previous versions of Linux, the screen by now simply stays black. Is this a known problem and if so is a fix available? -- .''`.

After reading this E-Mail I tested it on my notebook (TarvelMate800) and noticed that even with kernel 2.6.0 /proc/acpi/processor/CPU0/limit and /proc/acpi/processor/CPU0/performance disappeared. Kernel 2.4.23: ($:/)-> cat /proc/acpi/processor/CPU0/info processor id: 0 acpi id: 0 bus mastering control: yes power management: yes throttling control: no performance management: yes limit interface: yes Kernel 2.6.0: ($:/)-> cat /proc/acpi/processor/CPU0/info processor id: 0 acpi id: 0 bus mastering control: yes power management: yes throttling control: no performance management: no limit interface: no I don't use the performance option, since I throttle my notebook with cpufreq, but it still looks like a regression. /Michael ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.

Would you file it on > http://bugzilla.kernel.org I guess he needs rather to compile the ACPI performance CPUFreq driver and insmod acpi.ko, or something similar. That's a pretty non-obvious change over 2.4.
