Summary: Regression from 2.6.21: Can not use echo -n "5">/proc/acpi/sleep Product: ACPI Version: 2.5 KernelVersion: 2.6.24-rc4 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Power-Off AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] Most recent kernel where this bug did not occur:2.6.21 Distribution:xandros, debian Hardware Environment:Asus EeePC, Asus EP20 Software Environment: Problem Description:We had originally some problems using a regular "C" reboot(poweroff) call from our init C prog, however writing 5 to /proc/acpi/sleep worked OK. It was broken in 2.6.22, and still is in 2.6.24-rc4 Steps to reproduce: echo -n "5">/proc/acpi/sleep will fail with ENODEV, because in (2.6.24) kernel/power/main.c/valid_state(4)/suspend_ops->valid(state) returns NULL Call chain: valid_state() is called from drivers/acpi/sleep/proc.c/acpi_system_write() which calls drivers/acpi/sleep/main.c/acpi_suspend(5) which calls kernel/power/main.c/pm_suspend(4) which calls kernel/power/main.c/enter_state(4) which calls kernel/power/main.c/valid_state(4) -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
