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
