This is considered a firmware bug. To provide better warning message, this patch adds duplicated hardware error source ID detecting and corresponding printk. This patch fixes #37412 on kernel bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=37412 Reported-by: marconifabio@ubuntu-it.org Signed-off-by: Huang Ying <ying.huang@intel.com> Tested-by: Mathias <janedo.spam@gmail.com> Signed-off-by: Len Brown <len.brown@intel.com> 2011-07-13T18:49:09Z Rafael J.

Thus, when lockdep is enabled, it uses "lock" as the name of all those locks and regards them as instances of the same lock, which causes it to report possible locking problems with them when there aren't any. To work around this problem, define acpi_os_create_lock() as a macro and make it pass its argument to spin_lock_init(), so that lockdep uses it as the name of the new lock. Define this macron in a Linux-specific file, to minimize the resulting modifications of the OS-independent ACPICA parts. This change is based on an earlier patch from Andrea Righi and it addresses a regression from 2.6.39 tracked as https://bugzilla.kernel.org/show_bug.cgi?id=38152 Signed-off-by: Rafael J.

If OSPM has not indicated that it supports _PR3, then the value “3” corresponds to D3. If it has indicated _PR3 support, the value “3” represents D3hot and the value “4” represents D3cold. Linux does set _OSC._PR3, so we should fix it to expect that _SxW can return 4.
