The module i8042 fails on Pegasos: request_irq(I8042_AUX_IRQ, i8042_aux_test_irq, IRQF_SHARED, "i8042", i8042_platform_device) fails. Same with keyboard. It doesn't matter whether to compile i8042 into kernel or as loadable module.
Steps To Reproduce (via ssh or USB keyboard): modprobe i8042 debug dmesg output: drivers/input/serio/i8042.c: 24 <- i8042 (flush, kbd) [0] drivers/input/serio/i8042.c: aa -> i8042 (command) [0] drivers/input/serio/i8042.c: 55 <- i8042 (return) [0] drivers/input/serio/i8042.c: 20 -> i8042 (command) [0] drivers/input/serio/i8042.c: 44 <- i8042 (return) [0] drivers/input/serio/i8042.c: 20 -> i8042 (command) [0] drivers/input/serio/i8042.c: 44 <- i8042 (return) [0] drivers/input/serio/i8042.c: 60 -> i8042 (command) [1] drivers/input/serio/i8042.c: 54 -> i8042 (parameter) [1] drivers/input/serio/i8042.c: d3 -> i8042 (command) [1] drivers/input/serio/i8042.c: 5a -> i8042 (parameter) [1] drivers/input/serio/i8042.c: 5a <- i8042 (return) [1] drivers/input/serio/i8042.c: a7 -> i8042 (command) [1] drivers/input/serio/i8042.c: 20 -> i8042 (command) [1] drivers/input/serio/i8042.c: 74 <- i8042 (return) [1] drivers/input/serio/i8042.c: a8 -> i8042 (command) [1] drivers/input/serio/i8042.c: 20 -> i8042 (command) [1] drivers/input/serio/i8042.c: 54 <- i8042 (return) [1] drivers/input/serio/i8042.c: 60 -> i8042 (command) [1] drivers/input/serio/i8042.c: 74 -> i8042 (parameter) [1] drivers/input/serio/i8042.c: d3 -> i8042 (command) [1] drivers/input/serio/i8042.c: f0 -> i8042 (parameter) [1] drivers/input/serio/i8042.c: f0 <- i8042 (return) [1] drivers/input/serio/i8042.c: d3 -> i8042 (command) [1] drivers/input/serio/i8042.c: 56 -> i8042 (parameter) [1] drivers/input/serio/i8042.c: 56 <- i8042 (return) [1] drivers/input/serio/i8042.c: d3 -> i8042 (command) [1] drivers/input/serio/i8042.c: a4 -> i8042 (parameter) [1] drivers/input/serio/i8042.c: a4 <- i8042 (return) [1] drivers/input/serio/i8042.c: 60 -> i8042 (command) [1] drivers/input/serio/i8042.c: 74 -> i8042 (parameter) [1] drivers/input/serio/i8042.c: aa -> i8042 (command) [1] drivers/input/serio/i8042.c: 55 <- i8042 (return) [1] drivers/input/serio/i8042.c: 60 -> i8042 (command) [1] drivers/input/serio/i8042.c: 44 -> i8042 (parameter) [1] i8042: probe of i8042 failed with error -22

gentoo-sources-2.6.32-r20 works fine.
Same problem with 2.6.37
Can you please try with a vanilla kernel? If that doesn't help, can you do a git bisect so we can figure out which change broke it? http://www.reactivated.net/weblog/archives/2006/01/using-git-bisect-to-find-buggy-kernel-patches/ Thanks!

I did this. The patch which introduced the problem is 540c6c392f01887dcc96bef0a41e63e6c1334f01 is the first bad commit commit 540c6c392f01887dcc96bef0a41e63e6c1334f01 Author: Martyn Welch <martyn.welch@ge.com> Date: Mon May 24 22:09:16 2010 +0000 powerpc: Add i8042 keyboard and mouse irq parsing Currently the irqs for the i8042, which historically provides keyboard and mouse (aux) support, is hardwired in the driver rather than parsing the dts. This patch modifies the powerpc legacy IO code to attempt to parse the device tree for this information, failing back to the hardcoded values if it fails.

Thank you for bisecting the bad commit. That is this commit: http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=540c6c392f01887dcc96bef0a41e63e6c1334f01 Guess you can temporarily replace irq_of_parse_and_map(parent, 0) by 1 and irq_of_parse_and_map(parent, 1) by 12. If you need help with patching it then feel free to let us know. We're tracking upstream on this. Our CC at upstream might have brought attention to the bug; if not, I suggest you to poke it again in a week or so and later try to contact the kernel mailing list hoping people jump on the problem there. If all else fails two weeks to a month of now, feel free to ping us and / or reopen this bug so we can consider patching this in genpatches. Though we need to be careful not to break it for others doing so...
And ... code fix upstream. :)
