thank you all for help! as I already understood - in this topic users reports about DIFFERENT bugs (but the same sympthoms) - if you are lazy to read this topic above:1) if your dmesg log contains USB errors ('reset low speed USB device' or other) - try to physically unplug USB devices (mayby onboard keyboards in notebooks seen as like USB devices in some situations?) or re-plug to ANOTHER USB controller; try to use USB keyboard (another keyboard); try to disable legacy USB support in BIOS. This is kernel problem.2) if your dmesg log contains non-USB errors ('Unknown key released' or something else) -try to change the BIOS setting 'Plug and play OS' to it's default state ('No');try to disable WiFi adapter;try to disable OpenGl in KDE, Gnome, ... ;try to set atkbd.softrepeat=1 parameter to the kernel boot parameters in Grub;try to unload the battery, AC and thermal modules of kernel after booting;try to set acpi=off parameter to the kernel boot parameters in Grub;try to disable legacy USB support in BIOS;try to execute xset r rate 1000 50 command;try to set in BIOS do not check if PCI-express videocard not installed search for PCI video card, if not - try to initialize internal video card - instead of it set BIOS to initialize your existing video card first;try to disable auto-repeat keys in keyboard in KDE or Gnome settings;try to switch to another kernel;try to execute xmodmap /usr/share/xmodmap/xmodmap.us-101 each time the bug occurs;try to set highres=off nohz=off noapm parameters to the kernel boot parameters in Grub;try to remove gnome-sensors-applet , lm_sensors , net-snmp-libs , hplip , hpijs , net-snmp packages or packages with same functionality;try to edit /etc/mkinitcpio.conf and remove the word 'keyboard' from line HOOKS="... ;try to remove gnome-accessibility-themes , gnome-accessibility-themes-extras accessibility packages or packages with same functionality;try to remove hotkeys-setup package or package with same functionality;try to report at bugs.launchpad.net and ubuntuforums.org about this bug (include your list of hardware (lspci command) and Linux version (uname -a command) and dmesg log)This is a kernel problem also.useful links (are already listed above in this thread): _bug.cgi?id=9147 _bug.cgi?id=9448 +source/linux-source-2.6.15/+bug/39315 _bug.cgi?id=12021
