While that is different it does carry on; and, if I'm reading it right, the last thing it does in my 2.6.30 logs is enable the keyboard and then prod the mouse: [ 2.814817] drivers/input/serio/i8042.c: f4 -> i8042 (kbd-data) [13] [ 2.817615] drivers/input/serio/i8042.c: fa <- i8042 (interrupt, 0, 1) [14] [ 2.823470] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input1 [ 2.827716] evbug.c: Connected device: input1 (AT Translated Set 2 keyboard at isa0060/serio0/input0) [ 2.828278] drivers/input/serio/i8042.c: d4 -> i8042 (command) [17] [ 2.828427] drivers/input/serio/i8042.c: f2 -> i8042 (parameter) [17] The 'ack' to the f4 presumably means the keyboard is reasonably happy? That 'd4, f2' write-to-mouse times out on the 2.6.18 version, but no other 8042 debug comes out on the 2.6.30. Here's the matching 2.6.18: drivers/input/serio/i8042.c: d4 -> i8042 (command) [7] drivers/input/serio/i8042.c: f2 -> i8042 (parameter) [7] EISA: Probing bus 0 at eisa.0 EISA: Detected 0 cards.

Freeing unused kernel memory: 256k freed drivers/input/serio/i8042.c: fe <- i8042 (interrupt, AUX, 0, timeout) [19] drivers/input/serio/i8042.c: d4 -> i8042 (command) [19] drivers/input/serio/i8042.c: ed -> i8042 (parameter) [19] drivers/input/serio/i8042.c: fe <- i8042 (interrupt, AUX, 0, timeout) [31] drivers/input/serio/i8042.c: 60 -> i8042 (command) [31] drivers/input/serio/i8042.c: 44 -> i8042 (parameter) [31] (Although it's a bit difficult to compare since it seems 2.6.18 tends to do mouse first and only keyboard after the mouse times out).
