Hello, Pressing the eject key on my Dell Studio 1555 does not work and dmesg produces this message : dell-wmi: Unknown key 0 pressed Adding a debugging printk in dell-wmi.c after line 222 like this : printk(KERN_INFO "dell:wmi 0x%x , 0x%x \n", buffer_entry[1], buffer_entry[2]); dmesg now shows : dell:wmi 0x0 , 0xe009 dell-wmi: Unknown key 0 pressed So for some reason buffer_entry[1] is used although it is empty. Falling back to buffer_entry[2] in case buffer_entry[1] is 0x0 makes the button work. I suspect it might be better to fix the "dell_new_hk_type" logic though I had submitted this as https://bugzilla.kernel.org/show_bug.cgi?id=16075 but repeating the information and patch here as per Andrew Morton's suggestion. Thanks. --- linux-sidux-2.6-2.6.34/drivers/platform/x86/dell-wmi.c.orig 2010-06-03 01:02:17.418824168 +0400 +++ linux-sidux-2.6-2.6.34/drivers/platform/x86/dell-wmi.c 2010-06-03 01:01:40.641833249 +0400 @@ -221,7 +221,7 @@ static void dell_wmi_notify(u32 value, v return; } - if (dell_new_hk_type) + if (dell_new_hk_type || buffer_entry[1] == 0x0) reported_key = (int)buffer_entry[2]; else reported_key = (int)buffer_entry[1] & 0xffff; -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
