Hm. I am not. The Soekris is my only device with an E6xx CPU. This one is special, as Soekris does not implement ACPI. I don't know, how other E6xx systems do work. I guess, there will have ACPI. There seem not to be many out there. This patch is now running for about six months without any problems for me. I was also searching for some other systems. I found here only one manual. There are at least the same vendor/device id shown, as used also in Soekris. -> http://www.ekf.de/p/pc2/pc2_ug.pdf Is there maybe any possibility to check for the specific Soekris model? At least MPTABLE identifies the Soekris: [ 0.000000] MPTABLE: OEM ID: Soekris [ 0.000000] MPTABLE: Product ID: net6501 [ 0.000000] MPTABLE: APIC at: 0xFEE00000 Cheers Conrad -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
