Distribution: Fedora Core development (pre-FC4) Hardware Environment: PC, 32-bit Athlon, PS/2 keyboard Software Environment: KDM login manager Problem Description: I have a serial console attached on /dev/ttyS0 (it is another Linux machine). The serial console seems to work; however, if I boot up with the serial console enabled, a few seconds after starting to log in at the kdm login manager, the keyboard locks up, consistently every time. It is completely inoperable - I cannot switch to a virtual console with CTRL+ALT+F1, and the Num Lock key does not cause the Num Lock LED to light up. However, my PS/2 mouse still works fine. Steps to reproduce: Boot with the following grub command line kernel /vmlinuz-2.6.12-rc3 ro root=/dev/VolGroup00/LogVol00 noacpi elevator=cfq console=tty1 console=ttyS0,38400
If I instead boot into runlevel 3, the keyboard is fine until I do "init 5", at which point the problem reoccurs. If I go down to runlevel 3 from runlevel 5 (by typing "init 3" at the serial console) the keyboard is still locked up - even ctrl+alt+del does not work. (NOTE: I cannot see any virtual terminals because of an X.org virtual terminal restore corruption bug - but virtual terminal _input_ usually works after X has corruptly restored a virtual terminal: it's just the output that's corrupted. Therefore I believe the continuing keyboard lockup here is due to this bug, not due to the X.org bug.) I managed to workaround this bug one time by randomly banging on the keyboard :-) - but this workaround is not reproducable.
Robin, Does it work better with recent kernel/Xorg? Thanks.
Closing the bug. Please reopen if confirmed with latest kernel.
