From 80da76bc5041a75d882110b83cf10ca98ce646b8 Mon Sep 17 00:00:00 2001 From: sobomax Date: Thu, 7 Apr 2005 17:15:10 +0000 Subject: Provide a new tunable hw.atkbdc.broken_kit_cmd, which if set to 1 instructs the driver to avoid using Keyboard Interface Test command. This command causes problems with some non-compliant hardware, resulting in machine being abruptly powered down early in the boot process. Particularly it's known that HP ZV5000 and Compaq R3000Z notebooks are affected by this problem. Due to popularity of those models this patch is good MFC5.4 candidate.
