Dell laptops fail to send key up events for several of their special
keys. There's an existing quirk in the kernel to handle this, but it's
limited to the Latitude range. This patch extends it to cover all
portable Dells.

This issue has hit a lot of Ubuntu Dell uses (like myself), and the
patch indeed fixes it up - but it appears not all Dell machines are
alike. One user has reported it doesn't work, and his investigation
reveals dmicode output shows:
Vendor: Dell Computer Corporation
So I guess this isn't totally fixed yet. As to what the vendor output
is al all these machines, I don't know, but I guess now it could be any
permatation of Dell Inc., Dell Computer Corp. etc.

OK, I asked for help on this - so far it seems either Dell Inc. or Dell
Computer Corporation, so I guess this patch needs a || somewhere.

Matthew,
The original worked for me fine, and a lot of other people as our Dell
laptops produce 'Dell Inc.' as vendor. But other peoples return 'Dell
Computer Corporation' and thus it didn't work for them.
But how you determine if these certain laptops produce a keypress
release I don't know with having all of them at hand...
So it needs BOTH 'Dell Inc.' and 'Dell Computer Corporation' to cover
these laptops (I guess), as per the info I got from people running
dmidecode:

The quirk is only applied to a small number of keys which wouldn't want
autorepeat anyway, so it's pretty clearly harmless even if the hardware
works sanely.

That's what the patch adds. I don't have appropriate hardware to test.

Yes.
I have copied to the Ubuntu bug report (they already pushed out your
first patch) so hopefully people there can test it as I don't have this
hardware either.
BTW, what was it that produced this issue in the first place? All
previous kernel versions worked OK?
Thanks,
Nick

It's the switch from kbd to evdev in Ubuntu, I suspect.

OK, as discussed, I cannot test this, but my research leads to this to
be correct:
http://ubuntuforums.org/showthread.php?t=978973
Dell use vendor ID s either 'Dell Inc.' or 'Dell Computer Corporation'
exclusively.
So I think this can be officially submitted.

Hi Matthew,
I see this didn't make into the 2.6.28 release, and a lot of Ubuntu
users are being bitten by it - I also assume that the Ubuntu kernel
guys will not add it until it is officially applied, and they will then
backport it.
The Ubuntu bug report confirms this works OK for people:

Some Dells need the dell input quirk applied but have a different vendor
string in their DMI tables. Add an extra entry to cover these machines as
well.

Dmitry, any chance of getting this queued for .29? Probably suitable for

Yep, will send with the rest of stuff for .29. Thank you Matthew.
