dmesg: working keyboard
Hello, Just wanted to point out that this bug began to appear with 2.6.28 (apparently -5). See the bug in launchpad : https://bugs.launchpad.net/ubuntu/+bug/334249 Cordially, SD. (In reply to comment #3) > Just wanted to point out that this bug began to appear with 2.6.28 > (apparently > -5). See the bug in launchpad : https://bugs.launchpad.net/ubuntu/+bug/334249 Hi! Thank you. But I think that this is a bit different problem. My keyboard stops working just occasionally. While in the description you've posted it seems like it does every time. Additionally I'm sure that I had this problem with 2.6.26. Please, can someone tell me what should I do to get more information when it appears again? I can connect USB keyboard and try to get something from the running system. But I don't know what information could be useful. Thank you. Hi, Here is a record of the frequency of the bug on my own side, with the different kernel versions : 2.6.27-11 (or was it 26 ? the Ubuntu 8.10 default one, anyways) : happening about once a month 2.6.28-4/5 : about 33 % of the time, i'd say. This was during Jaunty's alphas. 2.6.28-11 : current jaunty, it almost always fails (worked like twice) I can barely give more accurate information, but if any devs needs additional info i can try to trigger the bug here and get the needed info. Cordially, SD. Could you please boot with i8042.debug and send me full dmesg of a boot with keyboard/touchpad not working? Hello altogether, i also have a Vostro 1510 and i can confirm this behavior like many others (you can ask Google). I tried several Kernels and several main Linux Distributions. Every configuration showed this keyboard/touchpad bug . Even Kernel 2.6.30_rc6-118 don´t work flawless. In RedHat Bugzilla i found a workaround to solve this problem: https://bugzilla.redhat.com/show_bug.cgi?id=490250 Add to grub these kernel parameters and the keyboard is always working after boot: i8042.reset i8042.nomux i8042.nopnp i8042.noloop It would be great, if anybody could solve this issue! BTW: Thanks a lot to all the people who are working on the Kernel -> great job! -Steve Hi Dmitry, I'll post you those files as soon as I got another machine from which I can ssh to mine once it's booted (should be in two weeks, i'm travelling right now). Thanks for your attention. Created attachment 21695 [details]

Sorry, the attached file is of cource a textfile. I forgot to choose the correct mime-type! :-( Again: this string below solved the problem for me! i8042.reset i8042.nomux i8042.nopnp i8042.noloop The following commit is supposed to fix this commit 9334e90d5ac5ee1fa6d8b75acb7c64a8907787d1 Author: Jiri Kosina <jkosina@suse.cz> Date: Tue Jan 6 01:35:45 2009 -0800 Input: i8042 - add Dell Vostro 1510 to nomux list Dell Vostro needs 'nomux' quirk, otherwise the touchpad misbehaves. Reported-by: Robert Kiwanuka <robert.kiwanuka@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Dmitry Torokhov <dtor@mail.ru> could you please verify whether 2.6.30 kernel works correctly without any additional kernel commanlidne options? Hello Jiri, thank you for that input! I will check Kernel 2.6.30 on weekend. Bye Hello Jiri, I'm running 2.6.30 #1 SMP Thu Jun 11 16:44:24 CEST 2009 x86_64 GNU/Linux and today I have experienced the problem again. Almost after a month. Unfortunately I don't have i8042.debug option enabled and therefore can't send more information. Thank you for your interest. Hello Jiri, i also checked Kernel 2.6.30 an i agree with Jan. Unfortunately the problem still exist if no Kernel-Parameter is given! If you need another dmesg-output, let me know! Cheers, Stefan Could you please provide output of 'dmidecode -t system' from the affected machine? Created attachment 22089 [details]
dmidecode output from affected machine
Attaching 'dmidecode -t system' output from affected machine. (I obfuscated serial number.)

Actually I only use i8042.reset and i8042.nomux and it works for me with 2.6.28-13-generic kernel in a Vostro 1310. Without them keyboard and touchpad sometimes don't run when i boot the system.

dmesg on Ubuntu 9.10 a3, i386, with 2.6.31-4
I couldn't check with 2.6.30, but it is totally fixed for me in 2.6.31-4-generic (ubuntu 9.10 i386 kernel, so not vanilla), with a Vostro 1510.
I attached a dmesg output just in case.
