| | | | | | | | | | | | | | | | | | | | | | dock's uevent reported itself, not ata. It might be difficult to find an ata device just according to a dock.

| * ACPI: fix hotplug raceZhang Rui2008-09-232-6/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hotplug notification handler and drivers' notification handler all run in one workqueue. Before hotplug removes an acpi device, the device driver's notification handler is already be recorded to run just after global notification handler. After hotplug notification handler runs, acpica will notice a NULL notification handler and crash. So now we run run hotplug in another workqueue and wait for all acpi notication handlers finish. This was found in battery hotplug, but actually all hotplug can be affected.

However, some boxes have this bit clear, have a valid ACPI_RESET_REG & RESET_VALUE, and ACPI reboot is the only mechanism that works for them after S3. This suggests that other operating systems may not be checking the RESET_REG_SUP bit, and are using other means to decide whether to use the ACPI reboot mechanism or not. Here we stop checking RESET_REG_SUP. Instead, When acpi reboot is requested, only the reset_register is checked. If the following conditions are met, it indicates that the reset register is supported. a. reset_register is not zero b. the access width is eight c. the bit_offset is zero http://bugzilla.kernel.org/show_bug.cgi?id=7299 http://bugzilla.kernel.org/show_bug.cgi?id=1148 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

In such case the EC device can't be initialized correctly, which causes that battery/AC adapter can't work normally. As the EC address space handler is not removed and the memory pointed by its input argument is already free, sometimes the kernel will also be panic when EC internal register is still accessed. But the windows can work well on such broken BIOS. Maybe it will be reasonable that OS ignores the AE_NOT_FOUND error returned by the EC _REG object and continues to initialize EC device on some broken BIOS. For example: the ACPI object in EC _REG method can't be found and status error code is AE_NOT_FOUND. http://bugzilla.kernel.org/show_bug.cgi?id=8953 http://bugzilla.kernel.org/show_bug.cgi?id=10237 lenb: we may find a more general solution to this in the future.
