Hello I have a new laptop, an ACER 5050-4697 that sells "South of the border" (from Mexico to Argentina) relatively inexpensive... It is new not only in the sense that I just got it, but also it is a new model with new chips mostly unsupported under Linux. you can see the log of my attempts at making Linux work on this box at http://www.df.uba.ar/~solari/acer.html (No shame, Acer can only get the 32bit Visa working on this AMD-64 machine and the BlueTooth device is not supported, although it is there...) I started with debian Etch 4.0 with kernel 2.6.18.4 and soon updated the kernel to the last stable release 2.6.22 (no patch). With both kernels I have ACPI problems at booting time. 2.6.18.4 does not find the battery hangs when installing the module ac.ko removing the module ac-.ko it hangs later when launching the daemon hald working under acpi=off on boot line 2.6.22 hangs at boot time with last words ACPI Exception (processor_core=0781): AE_NOT_FOUND, Processor Device is not present [20070126] works with acpi=off or acpi=ht you can find dmesg output at the link provided above. ACPI tables downloaded and recompiled without errors or warnings (did I miss soemthing?) You can find them in a tarball at: http://www.df.uba.ar/~solari/ACER/acpidsl.tgz I hope you can help me, thanks in any case Hernan PS: using Linux since version 0.99 -- Hernán Gustavo Solari, solari@xxxxxxxxx, http://www.df.uba.ar/~solari - 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
