Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org The problem gets worse when you do not have a PS2 controller on the machine at all. Kernel spews out a screenful of this message as it boots up. An easy way to get rid of these messages is to undefine KBD_REPORT_TIMEOUTS in pc_keyb.h. This still does not get rid of the delays caused by the timeouts. If I could figure out a way to reliably determine if the PS2 controller exists or not, I would like to get rid of the delays as well. -- Khalid Johannes Erdfelt wrote: > > On Fri, Sep 07, 2001, Krishnakumar B wrote: > > On Friday, 7 September 2001, KOCHI Takayoshi wrote: > > > Recently I noticed > > > > > > keyboard: Timeout - AT keyboard not present? > > > > I guess this happens because you are using a USB keyboard and the kernel > > looks for a PS/2 keyboard.
