Re: Dell Latitude E6400 'sluggish' keyboard response with ACPI enabled
Hi all, I found, that this problem is somewhat connected with wsmoused (don't know how). If you disable wsmoused then keyboard works without problems. Br, Tomas

I can't wait to try the diff. Unfortunately, I don't have time today or tomorrow, so you'll have to wait for potential feedback... Rogier: I experience the same thing. Among a couple of other dmesg@ mails, I sent the following mail in August: - Forwarded message from Martin Toft m...@martintoft.dk - Date: Wed, 5 Aug 2009 11:31:09 +0200 From: Martin Toft m...@martintoft.dk To: dm...@openbsd.org Subject: Re: Dell Latitude E6400, everything works, had to switch disk controller to ATA (from IRR) in BIOS to detect disk Some things I've discovered since I sent the dmesg: - The cdrom drive isn't detected when the disk controller is set to ATA in BIOS. This is also the case in Ubuntu Linux 9.04 (I dual-boot OpenBSD and Ubuntu). - The laptop's keyboard is very annoying in OpenBSD. With about 10-20 second intervals, either single key presses are lost or a key press is repeated 5-10 times. My guess is that it's an USB keyboard, and OpenBSD is probably not powering down (or up) the relevant USB controller properly in connection with halt (or boot). It's a wild guess, of course. As a non-expert, I unfortunately have no solution for the keyboard problem. I'm ready to test anything sent in my direction. Thanks for a great OS. Best regards, Martin - End forwarded message -

Where I originally noticed the problem very quickly after system startup, it now seems to have disappeared. I still see acpidump segfaulting (but I can't tell whether that's a related issue or not). Tested on GENERIC.MP built this morning. dmesg 4.6-current (Oct. 4, amd64) http://pastebin.com/f605fda4d acpidump 4.6-current (Oct. 4, amd64) http://pastebin.com/f45f19d9d (acpidump still segfaults when run; if desired, I have the core file saved) If I can be of help testing further, please let me know. Thanks for the quick response. Regards, Rogier
Dell Latitude E6400 'sluggish' keyboard response with ACPI enabled
While trying out a Dell Latitude E6400, I notice sluggish keyboard behaviour. This occurs both in 4.5 as well as the Oct. 2 snapshot (-current). In each case, I use the amd64 snapshots. The issues disappear when disabling ACPI via UKC. What I see is the following: some keypresses being 'missed', occasional repeats of keys pressed (though only once). Additionally, I sometimes see a briefly non-responsive mousepad in X. Trying acpidump(8) results in a segfault (and accompanying coredump). Are others seeing this as well? I included dmesg and acpidump output at the links below. Other than that, this laptop seems to work fine (but I wouldn't be surprised if Dell does some undocumented dark magic in its ACPI somewhere). Are others seeing this sort of issue as well or does anyone have a suggestion as to what to try? dmesg 4.6-current (Oct. 2 snapshot, amd64) http://pastebin.com/f40be7a33 acpidump 4.6-current (Oct. 2 snapshot, amd64) http://pastebin.com/f10da9f0c (acpidump segfaults when run; if desired, I have the core file saved) Any insight appreciated, Rogier

This fixes it. I need to come up with a way to get this in the tree
without breaking IBM T21.
