I updated http://bugzilla.kernel.org/show_bug.cgi?id=9663 with some checked kernel version: I checked these builds now: 2.6.23-acpi.git (~ Aug/Sep 07) with _and_ without acpi=off -> WORKS 2.6.24-rc6 from git with no cmdline-option -> works NOT 2.6.24-rc6 from git with acpi=off -> WORKS !! I'm running a openSuSE 10.3 with updated kernels, because of sound, wlan and acpi. I'm just compiling a checkout of rc7. Will report. If you need some lsmod/dmesg/acpidumps from these environments, drop me a note please. - 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
