When using virtual consoles, key presses often fail to register unless the key is pressed more than once. This has started since kernel upgrade from r8, and makes it impossible to enter passwords correctly. The weird behaviour seems to occur at random but once it has started on a particular console, it continues off and on: some keystrokes register and some do not. Switching to another console usually gives normal behaviour. It does not happen at all in X. Reproducible: Sometimes To test whether perhaps my keyboard was at fault, I substituted another one. It made no difference to the problem. In addition, I do not get this problem when I boot into Debian on the same machine using the same keyboard (Debian kernel is 2.6.26-1) nor did I notice it with 2.6.27-r8.

The only unusual activity since changing kernels was some drm buffer errors. That ought not to affect the keyboard but there does seem to be a connection: when I stopped X, a virtual console that had been misbehaving suddenly cleared.

Is X running while this problem occurs?
(In reply to comment #5) > Is X running while this problem occurs? > Yes. And if I stop X (either from the screen with ctrl-alt-backspace) or from a root console with /etc/init.d/xdm stop, the problem clears itself at once.
I have been testing this with my old kernel - r8 configured *without* the i810 module. In this configuration DRI is inhibited and there are no drm buffer errors (though drm does still register itself). BUT the console problem still occurs and still clears at once when I stop X. So it is X-related but not directly related to the drm errors, and it is not caused by the kernel upgrade from r8 to r10. Maybe it is caused by the upgrade of xorg-server to 1.5.3.
If it's realated to X we need your xorg.conf as well. Please attach it to this bug report. Thanks in advance :)

Same with kernel 2.6.28-gentoo-r5.
I am now using xorg-server-1.5.3-r6. The bug is still there.
Could you attach your full Xorg.0.log along with the full output of dmesg (in case anything appears in there). Thanks
Please get back to us. Thanks
Sorry, my last comment seems to have got lost. In fact I gave up using Gentoo some months ago - I've now migrated to Crux. So I don't have my Gentoo xorg.logs any more. I wish I could help you take this matter further but I'm no longer in a position to do so.
Reopening
Thanks for the follow up, even if you're no longer using Gentoo, we still appreciate it :) Closing
