It looks like the "Acer Aspire One 532h" and the "HP Pavilion dm3" have the same signature but they behave differently. As a result commit 5e28d8eb68 "Input: ALPS - add signature for HP Pavilion dm3 laptops" fixes things for dm3 but breaks the Acer Aspire One 532h which was working (with a userspace driver maybe??). Here is the relevant "i8042.debug" output from bz 15893: drivers/input/serio/i8042.c: d4 -> i8042 (command) [535] drivers/input/serio/i8042.c: e9 -> i8042 (parameter) [535] drivers/input/serio/i8042.c: fa <- i8042 (interrupt, 1, 12) [535] drivers/input/serio/i8042.c: 73 <- i8042 (interrupt, 1, 12) [536] drivers/input/serio/i8042.c: 02 <- i8042 (interrupt, 1, 12) [536] drivers/input/serio/i8042.c: 64 <- i8042 (interrupt, 1, 12) [536] What's the right way to handle this? regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
