Hi,
Last week I installed and configured FC4 (64 bits) on my athlon 64
bits (AMD 64 X2 4400+). It runs perfectly and quite swift. However,
within minutes after using the keyboard, the system *suddenly* starts
ignoring any keyboard input.
The mouse still works, and in so far I do not need keyboard input, I
can work.
Also, remotely, using SSH I can work normally.
This problem occurs only when using the SMP kernel (default for my
processor). Using the UP kernel I have no problem at all.
This error is repeatable, which renders the SMP kernel unusable to me.
Has anyone else suffered this problem?
Should I report it?
You should report it. 2.4.x kernels, single processor and SMP, never
give any trouble with mice or keyboards of the PS/2 or USB kind.
Things are really screwed up in 2.6.x, and are only slowly being
sorted out. I also have an X2 machine with an Asus A8N-E motherboard
(Nvidia nForce4-Ultra chip set). This seems to work OK with USB and
PS/2 keyboards using FC4. However, my dual Xeon machine with a Tyan
2665 motherboard only works properly using a single processor kernel.
With an SMP kernel it won't boot using a PS/2 keyboard.
A slight correction. The Tyan machine won't boot with an SMP kernel, a
PS/2 keyboard and USB enabled. If I disable USB it works. Apparently
using motherboards which allow legacy USB support to be disabled things
may work OK. The Tyan motherboard does not allow that. You either have
USB on or off. Nothing in between.
If you have selections of this kind in your BIOS, try then.
With a USB keyboard it kind of works, but it often doubles keys, or a
key gets stuck on until the next keypress, or it locks up completely
until I unplug and reinsert it. Various people have been reporting
problems of this kind since 2.6.x was first used. It happens with
vanilla kernels, as well as the ones supplied with FC4.
You may want to look at this bug which bit me
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=155759
After posting what I wrote earlier, I thought I would have another look
at the Tyan website. They now have a BIOS which does allow USB legacy to
be turned off. This is version 1.16. Their notes don't mention this
change, but after installing it I found the new option. I have been
using a PS/2 keyboard for the past few hours with no errors. This is
looking good. I suggest you try it. :-)
