Can you please have a look and advise? I can't even find the relevant code :/ >From that email I get kernfs_fop_write() which calls kernfs_get_active(), but that does _NOT_ call cpu_up(), so that callchain is shite. The actual lockdep splat is also not really helpful, and is spraying names over: acpi, device, sysfs and kernfs (do we really need that many layeres of obfuscation for a simple file?) So, please, start by explaining the thing proper such that simple people like me know what to look for. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
