Description of problem: I have ASUS M6R laptop (http://www.fi.muni.cz/~kas/m6r/), and the stock kernel in FC5 cannot use ACPI functions. Version-Release number of selected component (if applicable): kernel-2.6.15-1.2054_FC5 How reproducible: 100% Steps to Reproduce: 1. Boot the default FC5 kernel on ASUS M6R 2. run ls /proc/acpi/battery Actual results: the directory is empty (as well as some other ACPI directories) Expected results: the directory should contain battery status/info files, the rest of the ACPI interface should work. Additional info: dmesg output attached (see the ACPI AE_TIME errors) I think this is kernel.org bug #6111 (http://bugzilla.kernel.org/show_bug.cgi?id=6111) - at least when I compiled vanilla 2.6.16-rc6 it did not work as well, and after adding the patch mentioned in that bug it works correctly.
