--- Comment #10 from Pascal Dormeau <[email protected]> 2011-04-01 20:51:48 --- Created an attachment (id=53002) --> (https://bugzilla.kernel.org/attachment.cgi?id=53002) 2.6.38 dmesg with bf325f9538d8c89312be305b9779edbcb436af00 reverted Hello, I tested kernels from kernel.org: v2.6.37.6 -> OK v2.6.38.1 -> failed v2.6.38-rc1 -> failed With git bisect I could isolate the commit that results into the crash: commit bf325f9538d8c89312be305b9779edbcb436af00 Author: Rafael J. Wysocki <[email protected]> Date: Thu Nov 25 00:10:44 2010 +0100 ACPI / PM: Register power resource devices as soon as they are needed Depending on the organization of the ACPI namespace, power resource device objects may generally be scanned after the "regular" device objects that they are referred from through _PRn. This, in turn, may cause acpi_bus_get_power_flags() to attempt to access them through acpi_bus_init_power() before they are registered (and initialized by acpi_power_driver). [This is not a theoretical issue, it actually happens for one PnP device on my testbed HP nx6325.] To fix this problem, make acpi_bus_get_power_flags() attempt to register power resource devices as soon as they have been found in the _PRn output for any other devices. Signed-off-by: Rafael J. Wysocki <[email protected]> Signed-off-by: Len Brown <[email protected]> I could build and run a 2.6.38 kernel with the above commit reverted. It boots with no problem (with acpi support) The corresponding dmesg is in attachement Best regards Pascal Dormeau -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
